Diethylene glycol is quite similar to ethylene glycol in toxicity, although without production of oxalic acid. - Glucose, fructose and Sugars contain larger numbers of -OH groups but they are not termed as Glycols. Ethylene Glycol vs Diethylene Glycol: Ethylene glycol ແມ່ນເຫຼົ້າທີ່ມີສູດເຄມີ C2H6O2. | Catalyst: Both acidic and basic catalysts are used for the production of ethylene glycol. Freezing point being around -10 C it's not effective as a practical antifreeze. New Window. polyethylene glycol is a laxative and ethethylene glycol is anti-freeze. 0 0. Both have high boiling points, 245 and 290 C., respectively. Ethylene Glycol là gì 3. Similar to ethylene glycol, diethylene glycol is used in antifreeze, brake fluids, and deicing solutions. Only monoethylene and diethylene glycol show evidence of developmental toxicity. Casarett and Doull's Toxicology. Pumps head increased. In this case all the functional groups of the isopropyl alcohol and ethylene glycol molecules have identical pka(s), therefore no reaction can take place. To help you choose the correct glycol product please refer to the chart below.

Diethylene glycol induced histologic changes within the kidneys without kidney oxalate deposition. Polyethylene glycol is produced by the interaction of ethylene oxide with water, ethylene glycol, or ethylene glycol oligomers. Main differences between propylene glycol and ethylene glycol: Between the two ethylene glycol is a better heat transfer fluid than propylene glycol. Ethylene glycol is the most popular glycol in chemical industry. polyethylene has multiple ethyl groups ethylene has one. Viscosity: lower: higher: Propylene glycol increases major head loss in the systems. Small changes in structure can make a big difference in toxicity – just think of the difference between ethanol and the much more toxic methanol.
