Polyethylene glycol is a polyether composed of repeated ethylene glycol units [-(CH 2 CH 2 O) n]. PEG is a clear liquid or a water-soluble white solid with a mild odor. It can be either cationic polymerization or anionic polymerization. Polyethylene Glycol: Polyethylene glycol has many uses including medical uses, chemical uses, biological uses, industrial uses, etc. Terms of Use and Privacy Policy: Legal. Over a molecular weight of 900, it can be a white waxy solid, flakes or a powder. There are many nasty ingredients out there, but in this post I want to touch on two that I find particularly bad: Propylene Glycol and Polyethylene Glycol. Ethylene glycol solutions became available in 1926 and were marketed as “permanent antifreeze” since the higher boiling points provided advantages for summertime use as well as during cold weather. Although they have nearly similar names, polyethylene glycol and ethylene glycol are very different compounds depending on their chemical structures and general properties. Asia holds a prominent share in the global market production of MEG Ethylene Glycol: Ethylene glycol is mainly used for the manufacturing of polyester fibers and as an automotive antifreeze. The IUPAC name of ethylene glycol is ethane-1,2-diol, and its molecular formula is (CH2OH)2. Answer: The freezing points of these glycol solutions can be found in the tables below: Ethylene Glycol Solution (% by mass) 0: 10: 20: 30: 40: 50: 60: It has many industrial applications; it is used as an antifreeze coolant in hydraulic fluids and in the manufacturing of low-freezing dynamites and resins. A high yield (90%) can be obtained when the reaction occurs at acidic or neutral pH, in the presence of excess amount of water. During this process, ethylene oxide is produced as an intermediate, and it then reacts with water to produce ethylene glycol. Propyelene glycol is miscible with water as well as with chloroform and acetone. Both of them possess low vapor pressure, also they contain high boiling points and the ability to lower the freeze point of water. Its molar mass is 76.09 g/mol. Both Ethylene glycol and Polyethylene glycol are commercially very important and used in a number of applications. HOCH2CH2OH + n(CH2CH2O) → HO(CH2CH2O)n+1H.
