Diethylene glycol is rapidly absorbed and distributed to the kidneys, brain, liver, spleen, and adipose tissue. The results suggested that the renal tubular damage is due to a toxic metabolite, diglycolic acid, and that transporter-mediated uptake leads to toxic intracellular accumulation. It is used as a plasticizer, antifreeze, lubricant, and liquid fuel (e.g., Sterno Wick Chafing Fuel, Des Plaines, IL). The resulting product is two ethylene glycol molecules joined by an ether bond. Polyesters of low molecular weight with OH group contents ranging from 3 to 0.5 … The morning-only group also had better sleep quality and less interference with the previous workday. 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). It is also incompatible with strong bases. Diethylene glycol is a a four carbon dimer of ethylene glycol and finds applications as antifreeze, solvent, humectant, hydraulic fluid and brake fluid. The strongest support for this type of reaction, however, was obtained from kinetic data. Diethylene glycol is an organic, colorless, almost odorless, and poisonous chemical compound. DEG is primarily synthesized via the partial hydrolysis of ethylene oxide, and is co-produced with ethylene glycol and triethylene glycol. 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.

Unlike poisoning with ethylene glycol, the metabolic acidosis is not as prominent until renal toxicity is advanced. In the presented work to the synthesis of polyurethanes was used tri-functional polyether polyol based on the oxypropylated glycerol. Diethylene glycol succinate stationary phase is a non-volatile liquid phase. 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. DEG is a water-soluble liquid with a boiling point of 245 C. It is also soluble in many organic solvents. It is used in a wide variety of industrial applications, including as a compound in the manufacture of polyurethane plastic, in natural gas production, and as a solvent . HEAA is subsequently excreted by the kidneys. 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. DEG causes an anion gap metabolic acidosis that has been associated with significant historical poison outbreaks. Jump to main content Jump to site nav. The exact mechanism of renal toxicity, acidosis, and other aspects of the poisoning are unknown. Diethylene Glycol Market: Overview. Obtained hydroxyl-functional products were used to prepare the polyurethane coatings. The chemical … A glycol is an alcohol with two hydroxyl groups on adjacent carbon atoms (a 1,2-diol). Firstly, the oxalic acid diethylene glycol (OADEG) was synthesized by oxalic acid and ethylene glycol, and then copolycondensized with glycerol and phthalic anhydride. Diethylene glycol (DEG) is the by-product of the hydration of ethylene oxide. However, the number of studies was limited.

Both serve as solvents for the liquid-phase synthesis and surface-active agents for the formation of faceted microcrystals. 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]. 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 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. Polyp detection was greater and not inferior in the morning-only group. Use powder, alcohol-resistant foam, water spray, carbon dioxide. The animals developed metabolic acidosis as in ethylene glycol toxicity [51] and mortality was reduced if animals were treated with bicarbonate or ethanol. Diethylene glycol is an organic, colorless, almost odorless, and poisonous chemical compound. Diglycolic acid was recently identified to be the primary nephrotoxic metabolite in DEG poisoning.

Experimental studies in rats exposed to diethylene glycol clearly showed similarities with rats experiencing ethylene glycol toxicity [57,58]. Its solubility in both organic and aqueous solutions has resulted in its occasional incorporation into pharmaceutical elixirs, with tragic results. Availability of DEG depends on the demand for derivatives of the primary product, ethylene glycol, rather than on DEG market requirements. It is miscible in water, alcohol, ether, acetone, and ethylene glycol. 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. Diethylene glycol (DEG) is the by-product of the hydration of ethylene oxide. The volume of distribution of DEG is unknown in humans but is approximately 1 l kg −1 in rats. Whether the toxicity is a result of direct injury from DEG or a metabolite is still unclear.17,18 A DEG metabolite, 2-hydroxyethoxyacetic acid, has been identified in an animal model but has not subsequently been seen in humans.19 The treatment of DEG toxicity is aggressive symptomatic and supportive care and early hemodialysis. Marraffa, in Encyclopedia of Toxicology (Third Edition), 2014. 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.
