It may demonstrate electrophysiological findings consistent with a polyradiculopathy (Martinez-Miguel et al., 2006; Zhou et al., 2002). Split-dosing has therefore been studied in various randomized, controlled trials. It is derived as a co-product in the production of ethylene glycol. Marraffa, in Encyclopedia of Toxicology (Third Edition), 2014. DEG affects the CNS, heart, respiratory system, liver, pancreas, and kidneys. A Keggin-type heteropoly acid revealed high catalytic activities for the etherification of diethylene glycol with ethanol to synthesize diethylene glycol ether in the homogeneous phase. The poison epidemics previously listed have also been associated with liver toxicity, respiratory failure, and seizures. Copyright © 2020 Elsevier B.V. or its licensors or contributors. Obtained hydroxyl-functional products were used to prepare the polyurethane coatings. There is also great variability in susceptibility to diethylene glycol poisoning, suggesting pharmacodynamics and individual risk factors are important [12]. 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. When released to the atmosphere, vapor-phase diethylene glycol is degraded by reaction with photochemically produced hydroxyl radicals with an estimated half-life of 13 h. Diethylene glycol in air in particulate-phase may be removed by wet deposition. DIETHYLENE GLYCOL is incompatible with strong oxidizing agents. It is a potential neuro- and nephrotoxin for humans. PEGs can be synthesized in linear, branched, Y-shaped, or multi-arm geometries. 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. Phase pure Zn2GeO4:Mn2+ is obtained for the samples prepared at 0 ≤ xDEG ≤ 91.7, where xDEG is the volume percentage of DEG in the mixed solvent. Firstly, the oxalic acid diethylene glycol (OADEG) was synthesized by oxalic acid and ethylene glycol, and then copolycondensized with glycerol and phthalic anhydride. DEG is also commonly used in human medications, such as acetaminophen and sulfanilamide, either intentionally or accidentally leading to episodes of human poisoning, several being fatal. Diethylene glycol is an organic, colorless, almost odorless, and poisonous chemical compound. The resonance signals arising from aromatic protons in 1,n 1–3 were identified in 1H NMR spectra of TPA-DEG condensates. It is also incompatible with strong bases. 0.76 mL ACC–DEG slurry was injected into the reaction solutions and the samples were withdrawn periodically. Diethylene glycol (DEG) is employed as a comonomer during the synthesis of poly (ethylene terephthalate) (PET). Diethylene glycol is oxidized by ADH to 2-hydroxyethoxyacetaldehyde, which is further oxidized by ALDH to 2-hydroxyethoxyacetic acid (HEAA) [8,12]. In humans exposed to diethylene glycol, the presence of acidosis has been questioned, but this may be due to the fact that more emphasis has been given on pathological findings in these fatal cases than on clinical and metabolic features [60]. The half-life of DEG is dose dependent and doses of 6 ml kg−1 and 12 ml kg−1 in rats yielded a half-life of 8 and 12 h, respectively. J AOAC Int 81(1):44-50. Management of adverse drug reactions The use of intrathecal methylprednisolone in the treatment of postherpetic neuralgia is limited by the presence of polyethylene glycol as a preservative in the commercial formulation. N.H. Choulis, in Side Effects of Drugs Annual, 2014. 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. There is at least one clinical report of metabolic acidosis in children [61]. n = 0 ethylene glycol ("antifreeze") ; n = 1 DEG n = 2 triethylene glycol, TEG, or triglycol is also a colorless odourless viscous liquid. FREE Shipping on orders over $25 shipped by Amazon. Ethylene glycol, also called ethane-1,2-diol, the simplest member of the glycol family of organic compounds. Only 10 left in stock (more on the way). DEG is a widely used solvent. The resulting product is two ethylene glycol molecules joined by an ether bond. Diethylene glycol (DEG) is an organic chemical which is synthesized through the partial hydrolysis of ethylene oxide. have been synthesized by a low temperature chemical precipitation method. $21.40 $ 21. Kenneth Scott Whitlow, Kyle J. Gunnerson, in Critical Care Nephrology (Second Edition), 2009. The administration of ethanol reduced mortality to nil and prevented acidosis. The process consists of the oxidation of ethylene at a high temperature in the presence of a silver oxide catalyst. It is used as raw … HiMedia GRM10145-500ML Diethylene Glycol, 500 mL. PEG is also known as polyethylene oxide (PEO) or polyoxyethylene (POE), depending on its molecular weight.

Pathologic examination has demonstrated severe demyelination, with lesser axonal damage, of virtually all cranial and peripheral nerves sampled (Rollins, Filley, McNutt, Chahal, & Kleinschmidt-DeMasters, 2002). DGM 2 The particle and crystallite sizes … Poly(ethylene glycol) (PEG) is a synthetic, hydrophilic, biocompatible polymer with widespread use in biomedical and other applications. TCC’s Diethylene Glycol (DEG) is a straight-chain dihydric alcohol which is aliphatic terminated on both ends by a hydroxyl group. 4 (Oral), H302 STOT RE 2, H373 *Chemical name, CAS number and/ or exact concentration have been withheld as a trade secret Full text of H-statements: see section 16 J.M. Based on these data it is be reasonable to conclude that the toxicity and treatment of ethylene glycol and diethylene glycol toxicity are similar, at least in rats (a reasonably good animal model). It is completely miscible with water and many 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. All five patients died despite supportive treatment and bicarbonate replacement [62]. 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. Under normal conditions, diethylene glycol has no detectable odor; however, under high vapor concentrations, a slightly sweet odor may be detected. HEAA is subsequently excreted by the kidneys. It is synthesized through the partial hydrolysis of ethylene oxide. Industrially, DEG is used to manufacture polyurethanes, plasticizers, and polyester resins. The kidneys receive most of the DEG. Diethylene glycol is rapidly absorbed and distributed to the kidneys, brain, liver, spleen, and adipose tissue. 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. Structure, properties, spectra, suppliers and links for: Diethylene glycol, 111-46-6. From: Encyclopedia of Toxicology (Second Edition), 2005, J.M. 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. Product Name Diethylene Glycol (Reagent) Cat No. Diethyleneglycol dimethacrylate. TCC’s Diethylene Glycol is used as a dehydrating agent for natural gas; a raw material for the production of plasticizers and polyester resins; a humectant; a textile lubricant and coupling agent; a solvent in textile dyeing and printing; a constituent of hydraulic fluids; a plasticizer for paper, cork and synthetic sponges; a solvent in printing inks; a raw material for the production of esters used as emulsifiers, demulsifiers, and lubricants; and a selective solvent for aromatics in petroleum refining. Because of its toxicity, DEG is not allowed in food and drugs. Diethylene glycol monomethyl ether monolaurate (DGMEML) was synthesized via the reaction of diethylene glycol monomethyl ether (DGME) with methyl laurate (ML) by a new solid base catalyst of KF/CaO/AC, which was prepared by impregnation method using active carbon as carrier. Diethylene Glycol is a liquid packed in bulk, totes (IBC tanks) and drums. Mixtures with sodium hydroxide decompose exothermically when heated to 446° F. (NTP, 1992) Belongs to the Following Reactive Group(s) Alcohols and Polyols ; … It is synthesized through the partial hydrolysis of ethylene oxide. Untreated animals developed acute tubular necrosis with renal oxalate crystals deposits. Synthesized ACC was dispersed into diethylene glycol (DEG) with a concentration of 3.95 mg/mL. The clinical presentation, however, could easily have been interpreted as severe GBS. Diethylene glycol is one of several diols (hydrocarbon containing two alcohol groups). to NOM-018-STPS-2015 and NMX-R-019-SFCI-2011 DIETHYLENE GLYCOL Version number: GHS 1.0 Date of compilation: 2017-05-03 Mexico: en Diethylene Glycol is sweet to the taste and is miscible in water , alcohol , ether and acetone.

In poisoned humans, characteristic findings include delayed-onset renal failure with vacuolar nephropathy and acute tubular necrosis, and centrilobular hepatic necrosis following single or subacute ingestion of about 1 g/kg. Diethylene Glycol Spec TCC – Click Here To Download. As is evident from the discussion above, diethylene glycol poisonings should be treated as recommended for ethylene glycol poisonings. diethylene glycol, etc ; crosslinking; crystals; gels; nanocapsules; polyethylene glycol; polymerization; pyrogallol; ... An unsaturated polyester resin was synthesized and filled with Cloisite 10A nanoparticles. 4 (Oral), H302 STOT RE 2, H373 Ethylene glycol (CAS No) 107-21-1 < 1 Acute Tox. The animals developed metabolic acidosis as in ethylene glycol toxicity [51] and mortality was reduced if animals were treated with bicarbonate or ethanol. 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. Various combinations of (a) maleic anhydride and phthalic anhydride, (b) propylene glycol and ethylene glycol, and (c) propylene glycol and diethylene glycol were used to investigate the effect on the properties of the synthesized resin. Synonyms:. Di(ethylene glycol) dimethacrylate. 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. In contrast, there was no increase in the risk of acute renal insufficiency attributable to polyethylene glycol in a case-crossover study using information obtained from Korean Health Insurance Review and Assessment Service claims relating to 1 093 262 elderly patients; among 1156 cases of acute renal insufficiency polyethylene glycol was prescribed for 17 patients before presentation (OR for exposure 2 weeks before presentation = 0.4; 95% CI = 0.03, 5.2; OR for exposure 4 weeks before presentation = 2.1; 95% CI = 0.16, 28) [63C]. 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. Please call (401) 360-2800 for details. Except for the lack of oxalate crystals, the pathological findings in the various organs of these victims were much the same as those found in ethylene glycol-poisoned victims. Microencapsulation of PRS paraffin wax was carried out by means of suspension-like homopolymerization of methyl methacrylate (MMA) and by the copolymerization of this monomer with methyl acrylate (MA) and methacrylic acid (MAA).
