Sometimes, people confuse propylene glycol with ethylene glycol. Their chemical structures are similar, and both are used in antifreeze, but they’re not the same. In antifreeze, propylene glycol lowers the freezing point of water, which keeps the antifreeze product liquid. It replaces ethylene gl...
Conversion of natural glycerin to propylene glycol through an acetol intermediate is achieved at temperatures from 150° to 250° C. at pressures from 1 and 25 bar. The preferred applications of the propylene glycol are as an antifreeze, deicing compound, or anti-icing compound. The preferred ...
Mono propylene glycol is produced from propylene oxide. The most common process is by the non-catalytic hydrolysis of propylene oxide in a high-temperature and high-pressure environment. The second method is the catalytic one, which can proceed at 150 °C, in the presence of ion exchange resin...
kidney failure in dogs, while as little as 1 teaspoon can be fatal to cats. When dogs or cats are exposed to a toxic dose of ethylene glycol, immediate treatment is necessary. Some “pet-safe” antifreeze products containpropylene glycol, which is much safer than ethylene glycol if ingested...
Polyethylene glycol (PEG) is made from ethylene glycol (ethane-1,2-diol), the main ingredient in antifreeze. When ethylene glycol (molecular weight, 62.07) polymerizes, reacts with itself (in water), the reaction yields a variety of products containing varying numbers of ethylene glycol units....
I have also found foods that contain antifreeze =propolene glycol. It is used as a cheap sweetner and an anti-freezing agent. Please check what you are consuming ,some ingredients are hardcore drugs #1 is caffeine it is a replacement for cocaine. Log in to Reply Em October 12, 2016 ...
What are the uses of glycol?Ethylene glycol is widely used as antifreeze in automobile cooling systems and in the manufacture of human-made fibres, low-freezing explosives, and brake fluid. Ethylene glycol and some of its derivatives are mildly toxic.Why is propylene glycol a good solvent?
The two most common compounds found in antifreeze and de-icing solutions are ethylene glycol and propylene glycol. The former has been identified as posing a danger to pets, but propylene glycol is much safer than ethylene glycol — it has been classified by the Food and Drug Administration (...
Diethylene glycol, which is an ingredient in antifreeze[3,4] Nitrosamines,[3,4]which are linked to cancer.[6] Potentially toxic carbonyls, including formaldehyde, acetaldehyde, acetone, and butanol.[9]One study found that with vaping, the exposure to formaldehyde is five to 15 times higher th...
“The secondingredientin these little bottles is propylene glycol, a preservative, thickening agent, and stabilizer, also used as antifreeze to de-ice airplanes, as a plasticizer to make polyester resins, and found in electronic cigarettes.” [Source] ...
