Wei Connaught Chemical, Qingdao factory _ glycol ethylene glycol plant _ provided by Wei Connaught Chemical. We are Qingdao Wei Connaught Chemical Co. (www.qdweinuo.com) at: Qingdao, Shandong specialized in: phenol, aniline, ethylene, n-butanol, isobutanol, n-propanol, isopropanol, methanol, ethylene why displayed low freezing point of alcohol? There are a lot of people think that low freezing point of ethylene glycol, the freezing point of antifreeze is mixed in different proportions according to a post in and freezing glycol purposes, it is not true, after mixing due to changes in the cooling water from the glycol and water vapor pressure , will significantly reduce the freezing point. After my company several tests: ethylene glycol antifreeze in the market when glycol and water accounting for 50%, the freezing temperature of -35 ℃: 40% of ethylene glycol and 60% of the water softener mixed into antifreeze, antifreeze temperature is -25 ℃. This temperature is sufficient to meet any regional domestic automobile antifreeze antifreeze requirements, as contained refrigerant unit without any problems. Common name glycol ethylene glycol plant, widely used, can be used to synthesis "Polyester" (Dacron) and other polymers, but also can be used as a film, rubber, plasticizers, desiccant, brake oil, raw materials, but also high-boiling solvent used. Because of low molecular weight, lively nature, can play esterification / ether / Aging / Oxidation / Acetal / dehydration reaction. Diethylene glycol, also known as diethylene glycol, a colorless transparent liquid without mechanical impurities.
