Glycol Preparation: Metals are generally dissolved in glycols, only monohydric alcohols; salts such as this alkoxide (e.g., sodium ethylene glycol) was heated to 180 ~ 200 ° C in a stream of hydrogen, may be formed of ethylene glycol bis sodium and ethylene glycol. Also with ethylene glycol and two moles of sodium methoxide were heated together glycol polyester resin, available disodium ethylene glycol. Disodium ethylene glycol is reacted with an alkyl halide to produce ethylene glycol monomethyl ether or bis ether. Disodium ethylene glycol with a price, 2-dibromoethane reaction of dioxane. Furthermore, ethylene glycol is also easily oxidized, with the oxidizing agent or reaction conditions different, can generate a variety of product glycol refrigeration, such as glycolaldehyde HOCH2CHO, glyoxal OHCCHO, glycolic HOCH2COOH, oxalic HOOCCOOH and carbon dioxide and water. Ethylene glycol and other glycol different, by periodate oxidation of carbon-strand breaks can occur. Application glycol instead of glycerin can often use glycol: Physical properties edit acetone formula [3] Relative density (water = 1): 0.788 Relative vapor density (air = 1): 2.00 saturated vapor pressure (kPa): 53.32 (39.5 ℃) heat of combustion (kJ / mol): 1788.7 critical temperature (℃): 235.5 critical pressure (MPa): 4.72 logarithm of the octanol / water partition coefficient: -0.24 explosive limit% (V / V): 13.0 ignition temperature (℃): 465 lower explosive limit% (V / V): 2.5 Solubility: miscible with water, soluble in most organic solvents such as ethanol, ether, chloroform, oils, hydrocarbons, etc. Industrial-grade ethylene glycol, ethylene glycol Lacey, Wei Wei Connaught Chemical provided by Qingdao Sino Chemical Co.
