Wei Connaught Chemical, Qingdao Chemicals Factory _ ethylene glycol shop _ jiaonan 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 Qingdao Overall Characteristics of alcohol: polymer of ethylene glycol polyethylene glycol (PEG) is a phase-transfer catalyst is also used for cell fusion. Ethylene glycol (ethylene glycol), also known as "glycol." Shandong glycol Appearance: colorless, sweet, viscous liquid. Ethanol, ethylene glycol and similar effects can be generated mainly inorganic or organic acid and esters, generally the first and only one hydroxyl group reacts by increasing the temperature, increasing the amount of acid, such as ethylene glycol, can have two hydroxyl groups to form esters. Ethylene glycol is a colorless, slightly viscous liquid, the boiling point is 197.4 ℃, freezing point is -11.5 ℃, can be mixed with water in any proportion. Due to changes in vapor pressure of the cooling water, the freezing point significantly reduced mixing. Degree of reduction within a certain range with the content of the ethylene glycol increases. When the content of ethylene glycol is 60%, the freezing point can be lowered to -48.3 ℃ glycol store more than this limit, the freezing point but to rise. Glycol antifreeze easy to generate, in use, the acidic substance, a pair of metal corrosion. Glycol toxic, but because of its high boiling point of ethylene glycol plant will not produce vapor being inhaled and cause poisoning. Glycol absorbent, storage containers should be sealed to prevent water overflow after. Since the boiling point of water is lower than ethylene glycol, the use of the water is evaporated, when a lack of coolant, just add water purifier on the line.
