The clinical course and the pathological features have, however, been described in several reports of which the sulfanilamide “Massengil disaster” is probably the best known [55]. 4 (Oral), H302 STOT RE 2, H373 Ethylene glycol (CAS No) 107-21-1 < 1 Acute Tox. Gd 1.9 Eu 0.1 O 3 nanophosphor with enhanced photoemission is successfully synthesized by a controlled combustion method of metal-citrate complex in diethylene glycol medium. A human infant fatality has been reported following ingestion of 3.6 g. After ingestion, diethylene glycol is rapidly absorbed, and 40% to 70% is excreted unchanged in the urine. DEG is a potent renal toxin that can cause a progressive and profound anion gap metabolic acidosis. Product Name Diethylene Glycol (Reagent) Cat No. Diethylene glycol (DEG) is a sweet-tasting, colorless, nonodoriferous, hygroscopic liquid commonly used in the commercial preparation of antifreeze, brake fluid, cigarettes, and some dyes. In the Haiti outbreak, the maximum possible median toxic dose was 1.5 g/kg (95% confidence interval 0.25 to 4.9 g/kg).62 In serious poisonings, headache, dizziness, CNS depression, anorexia, nausea, vomiting, diarrhea, and abdominal pain are commonly seen within 24 hours after ingestion. The morning-only group also had better sleep quality and less interference with the previous workday. The kinetic parameters of the synthesized and filled unsaturated polyester resins were calculated by an advanced isoconversional method and using dynamic DSC data. Synthesized specifically to be purer, of narrow molecular weight range, and without trace catalysts or impurities for use as a GC stationary phase. Poly(ethylene glycol) (PEG) is a synthetic, hydrophilic, biocompatible polymer with widespread use in biomedical and other applications. Availability of DEG depends on the demand for derivatives of the primary product, ethylene glycol, rather than on DEG market requirements. With a 4 hour burn time, each fuel can will cook from four to six meals at a steady heat level with little fluctuation. Diethylene Glycol is a liquid packed in bulk, totes (IBC tanks) and drums. Similar to EG, DEG is not toxic but its metabolites are. DIETHYLENE GLYCOL is incompatible with strong oxidizing agents. In this paper, we introduce the applications and … Unfortunately, outbreaks continue to occur in developing countries following the inadvertent substitution of diethylene glycol for PG or glycerin in elixirs usually intended for children, with mortality rates of 40% to 100%.60–64 (Table 32C-2) The oral LD50 ranges from 4.9 g/kg (rabbits) to 28.2 g/kg (mice), but is only 1.1 to 2.2 g/kg in mice when given intravenously. Toxicokinetics. 242 DP, … It can react with sulfuric acid and other dehydrating agents, nitric acid, oxygen, hydrogen peroxide, perchloric acid and strong acids. Diethylene glycol (DEG) is an organic compound with the formula (HOCH2CH2)2O. n = 0 ethylene glycol ("antifreeze") ; n = 1 DEG n = 2 triethylene glycol, TEG, or triglycol is also a colorless odourless viscous liquid. adipic acid, and diethylene glycol and zinc acetate as a catalyst. Zn2GeO4:Mn2+ nanophosphors are synthesized from germanium(IV) oxide and acetates of zinc and manganese(II) in a mixed solvent of water and diethylene glycol (DEG) by the solvothermal reaction at 200 °C for 2 h.

DEG is produced by the partial hydrolysis of ethylene oxide. J AOAC Int 81(1):44-50. The combinations of the anhydrides and glycols that give optimum properties are identified. Polyethylene glycol significantly increased the number of satisfactory bowel preparations and the willingness to repeat the same preparation compared with full-dose polyethylene glycol. The influence of diethylene glycol … Diethylene glycol is extensively used as a solvent for resins, paint pigments, oils, textile dyes, and printing. Ethylene glycol (EG) is an important organic compound and chemical intermediate used in a large number of industrial processes (e.g. The exact mechanism of renal toxicity, acidosis, and other aspects of the poisoning are unknown. From 1H Structure, properties, spectra, suppliers and links for: Diethylene glycol, 111-46-6. It has been proposed that by reducing the polyethylene glycol content, methylprednisolone-related complications might be reduced; the amount of polyethylene glycol can be reduced by 85% by inverting the vial to promote partition of the polyethylene glycol before aspirating the contents into a syringe for injection [67E]. It is synthesized through the partial hydrolysis of ethylene oxide. Diethyleneglycol dimethacrylate. Diethylene glycol, or DEG, is a colorless, liquid organic compound at room temperature produced by the interaction of ethylene glycol and triethylene glycol. It is miscible in water, alcohol, ether, acetone, and ethylene glycol. Acute kidney injury is usually the main cause of death, appearing between 8 and 24 hours after exposure to lethal doses of diethylene glycol [8]. The product is completely soluble in water, acetone, alcohol, and other organic solvents. It is a water-soluble liquid; boiling point 245 C; soluble in many organic solvents. TCC’s Diethylene Glycol is available for shipping throughout the continental United States with one (1) week lead time. Diethylene glycol is synthesized from the reaction of ethylene oxide with Ethylene glycol, in this case Diethylene glycol can contain Ethylene glycol EG also as toxic impurity (9,8,10). The strongest support for this type of reaction, however, was obtained from kinetic data. HiMedia GRM10145-500ML Diethylene Glycol, 500 mL. $21.40 $ 21. It is also used as a humectant in the tobacco industry and in the treatment of corks, glue, paper and cellophane as well as in the synthesis of morpholine and 1,4-dioxane. In addition to dialysis and ADH inhibition, the need for intensive care to multiple patients with multiorgan failure may overwhelm a health care system in the context of an outbreak.62,64, Jeffrey A. Cohen, ... Elijah W. Stommel, in Nerves and Nerve Injuries, 2015. It is completely miscible with water and many Mentioned polyol has trade name Rokopol G1000 and is produced by PCC Rokita in Poland. The remainder is oxidized to 2-hydroxyethoxy acetic acid by ADH and aldehyde dehydrogenase, which may esterify under physiologic conditions to the cyclic lactone p-dioxanone, a nonacid.65,66 The parent ether link is stable in vivo, accounting for the absence of ethylene glycol, glycolate, and glyoxalate in animal toxicity studies, and the inconsistent observation of oxalate in human cases.65–68 Lactic acid accounts for a substantial portion of the metabolic acidosis.69 Pyrazole and ethanol both reduce but do not eliminate the toxicity in animal models,69 suggesting that the parent compound is also toxic. Ethylene glycol (EG) is an important organic compound and chemical intermediate used in a large number of industrial processes (e.g. Synthesized ACC was dispersed into diethylene glycol (DEG) with a concentration of 3.95 mg/mL. The volume of distribution of DEG is unknown in humans but is approximately 1 l kg −1 in rats. Until more data are available, ethanol, not 4-methylpyrazole, should be used in order to prevent the assumed formation of toxic metabolites by alcohol dehydrogenase in the liver. When released to soil or water, diethylene glycol is highly mobile; adsorption to soil and sediment is very low; volatilization is not expected to be important. DEG affects the CNS, heart, respiratory system, liver, pancreas, and kidneys. DEG is a widely used solvent. 0.76 mL ACC–DEG slurry was injected into the reaction solutions and the samples were withdrawn periodically. The use of diethylene glycol to dissolve the early sulfa drug sulfanilamide by the Messengill company in 1937 resulted in 105 deaths, and triggered a national outcry.59 This tragedy led to the federal Food, Drug and Cosmetic Act in 1938, which initiated the close regulation of the safety of medicinals by the Food and Drug Administration. However, the number of studies was limited. All five patients died despite supportive treatment and bicarbonate replacement [62]. The neurophysiological assessments and the high CSF protein in this case suggest a polyradiculoneuropathy with features of conduction block (median, peroneal nerves), subsequently showing progression to severe, sensorimotor axonal loss in the patient’s legs; the motor axonal loss is more prominent in the more distal muscles (Alzouebi, Sarrigiannis, & Hadjivassiliou, 2008). Topical application of silver sulfadiazine contaminated with diethylene glycol to patients with burns resulted in an increased anion gap metabolic acidosis and acute renal failure. A patient in an acute condition appears inebriated but has no alcohol on his or her breath. MEG is the raw material used in the production of polyester fiber, PET resins, alkyds, and unsaturated polyesters. Immunologic The choice of a topical glucocorticoid in patients with allergic contact dermatitis due to polyethylene glycol has been discussed [64R]. Toxic effects can include abdominal pain, vomiting, diarrhea, headache, altered mental status, and acute kidney injury [8,12]. PEG is also known as polyethylene oxide (PEO) or polyoxyethylene (POE), depending on its molecular weight. DAG JACOBSEN MD, PHD, ... MARCO L.

Poly(ethylene glycol) (PEG) is a synthetic, hydrophilic, biocompatible polymer with widespread use in biomedical and other applications. DEG is a widely used solvent. It is miscible in water, alcohol, ether, acetone, and ethylene glycol. DEG poisoning shows extensive tubular necrosis; however, the oxalate deposition is of EG poisoning, which causes renal and cerebral damage, and has not been observed in DEG poisoning. Under normal conditions, diethylene glycol has no detectable odor; however, under high vapor concentrations, a slightly sweet odor may be detected. 40. It can react with sulfuric acid and other dehydrating agents, nitric acid, oxygen, hydrogen peroxide, perchloric acid and strong acids. Diethylene glycol was rapidly distributed throughout all organs and tissues following administration with maximum levels in kidney and minimum levels in the adipose tissue, and excreted mainly unchanged through urine. When consumed, DEG causes severe systemic and neurologic complications, including coma, seizures, peripheral neuropathy, and hepatorenal failure. In the presented work to the synthesis of polyurethanes was used tri-functional polyether polyol based on the oxypropylated glycerol. The resulting product is two ethylene glycol molecules joined by an ether bond, Diethylene glycol is derived as a co-product with ethylene glycol and triethylene glycol. In addition, it is used as a raw material to … See more. PEGs are synthesized using a ring-opening polymerization of ethylene oxide to produce a broad range of molecular weights and molecular weight distributions (polydispersity); however, discrete PEGs (dPEG ®) are synthesized with a single, specific molecular weight. The kidneys receive most of the DEG. Simply place a can in your cook stove, unscrew the cap, and light the wicks. PEG is the basis of a … The animals developed metabolic acidosis as in ethylene glycol toxicity [51] and mortality was reduced if animals were treated with bicarbonate or ethanol. However, the results have been conflicting. The difference between ethylene glycol and diethylene glycol is that an ethylene glycol molecule is an individual molecule whereas diethylene glycol molecule is formed by the combination of two ethylene glycol molecules via an ether bond. 2358-84-1. Other uses Dehydrating agent. It is an excellent solvent for many relatively insoluble substances. Polyesters of low molecular weight with OH group contents ranging from 3 to 0.5 … Diethylene glycol, CH2OHCH2OCH2CH2OH, is similar in properties to MEG (mono ethylene glycol), but DEG has a higher boiling point, viscosity, and specific gravity. Mixtures with sodium hydroxide decompose exothermically when heated to 446° F. (NTP, 1992) Histopathology of kidney tissue demonstrates acute tubular necrosis with regeneration and interstitial edema. D. Jacobsen, K.E. Nephrotoxicity (tubular necrosis) is the prominent feature in animal poisoning studies. Direct quantitation of diethylene glycol and HEAA in serum, urine, and CSF has also been reported, but there is limited clinical guidance on how to use this information beyond confirming exposure [31]. Preparation of the total colon was adequate in 92% in the morning-only group versus 94% in the split-dose group and preparation of the right colon was adequate in 93 and 92% respectively. Production of diethylene glycol is generally based on the demand for, and production of, monoethylene glycol as it is a by-product of this production process. Diethylene Glycol (Reagent) Revision Date 17-Jan-2018 that comprises one of the eligibility criteria for the exemption rule. A new class of diethylene glycol tethered moxifloxacin–isatin hybrids 5a–l was designed, synthesized, and evaluated for their in vitro antimycobacterial activity against Mycobacterium tuberculosis (MTB) H37Rv and multidrug‐resistant tuberculosis (MDR‐TB) strains. Synthesized ACC was dispersed into diethylene glycol (DEG) with a concentration of 3.95 mg/mL. ThermaFuel diethylene glycol fuel cells by Legacy are the preppers choice in emergency fuel. Some evidence of this type of reaction is given by the formation of dioxane in low molecular PET and of methyl Cellosolve and methyl carbitol during the ester interchange of DMT with ethylene glycol and diethylene glycol, respectively. Synthesis of Diethylene Glycol Terephthalate Polyester Polyols Statistical Oligocondensation Condensation of TPA with DEG in a 1:2 molar ratio was carried out at 225–230 °C. A total of 105 deaths due to renal failure were related to this sulfonamide formulation. The addition of Tyzor PC-42 catalyst increased the rate of esterification and shortened the distillation time to about 2 h (runs 2 and 3). Maurer HH, Peters FT, Paul LD, Kraemer T [2001]. Bioaccumulation of diethylene glycol in aquatic organism is expected to be low due to an estimated bioconcentration factor of 0.05. It is a colorless, practically odorless, poisonous, and hygroscopic liquid with a sweetish taste. Diglycolic acid was recently identified to be the primary nephrotoxic metabolite in DEG poisoning. Diethylene glycol definition, a syrupy colorless liquid, C4H10O3, used as a solvent for nitrocellulose and as a fabric softener. Diethylene glycol is an organic, colorless, almost odorless, and poisonous chemical compound. Autopsy was performed in one patient with no evidence of oxalate crystals. Polyp detection was greater and not inferior in the morning-only group. Laboratory findings in clinical assessment of diethylene glycol can include an elevated osmolar gap, elevated anion gap, elevated creatinine, and acidosis [8,11,12]. Nanoparticle formation features in a diethylene glycol solution using metal nitrates as starting compounds are discussed based on NMR data.
