There are a number of benefits using ethylene glycol over propylene glycol, especially in closed loop systems were risk of contact with food is minimal. Origin. 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. In the chemical industry, says MEGlobal's CEO, everything begins with ethylene. China consumes more than 50% of global ethylene glycol production, and it imports about a quarter of the world supply. 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. It is a colorless, practically odorless, poisonous, hygroscopic liquid with a sweetish taste. In untreated adults, approximately 20% of a dose of ethylene glycol is excreted unchanged by the kidneys. Ethylene glycol is rapidly absorbed from the gastrointestinal tract and slowly absorbed through the skin or lungs. It is primarily used as a raw material to produce polyester fibers for the fabric industry, and polyethylene terephthalate resins (PET) used in the bottle industry. Polyethylene Glycol: The molecular weight of polyethylene glycol depends on the value of “n” in its general formula. Ethylene glycol is a chemical compound that has an alcohol with two -OH groups. ethylene glycol a solvent with a sweet, acrid taste, used as an antifreeze. Mono Ethylene Glycol is used as solvent couplers, chemical intermediates for resins, and humectants. With the ability to lower the freezing point of water, it can prevent your engine from freezing over – but it can also be very dangerous. Ethylene glycol (IUPAC name: ethane-1,2-diol) is an organic compound with the formula (CH 2 OH) 2.It is mainly used for two purposes, as a raw material in the manufacture of polyester fibers and for antifreeze formulations. Immediate steps should be taken to limit its spread to the environment. Apart from this, it also plays a crucial role in the production of coolants, antifreeze and solvents. Ethylene Glycol (C2H6O2) - Ethylene glycol is the first member of the series of alkane diols and is also known as glycol. Diethylene Glycol is produced as a co-product of Ethylene Glycol and Triethylene Glycol. Diethylene glycol (DEG) is an organic compound with the formula (HOCH2CH2)2O. However studies have shown that metabolism to significant amounts of ethylene glycol does not occur, and that the type of renal toxicity seen with DEG is different than what is seen with ethylene glycol. Diethylene glycol, CH2OHCH2OCH2CH2OH, is similar in properties to MEG (mono ethylene glycol), but DEG has a higher … It and its toxic byproducts first affect the central nervous system (CNS), then the heart, and finally the kidneys. Antifreeze. Ethylene glycol (IUPAC name: ethane-1,2-diol) is an organic compound with the chemical formula (CH 2 OH) 2. Ethylene glycol (EG) is the organic compound commonly used in antifreeze.
