Ethanol, ethylene glycol and similar prices, mainly inorganic or organic acid can be generated with a glycol ester resin, usually the first and only one hydroxyl group reacts by increasing the temperature, increasing the amount of acid, etc., can have two hydroxyl groups to form esters. Such as nitric acid mixed with sulfuric acid in the reaction with the formation dinitrate. Acid chloride or anhydride is easy to make two hydroxyl groups to form an ester. Ethylene glycol under (manganese dioxide, aluminum oxide, zinc oxide or sulfuric acid) catalyst is heated, may occur intramolecular or intermolecular dehydration. Glycol with an alkali metal or alkaline earth metal alkoxides action. Glycol: Moore refractive index: 15.97 2, molar volume (cm3 / mol): 75.1 3, isotonic hematocrit (90.2K): 156.5 4, surface tension (dyne / cm): 18.8 5, polarization (10-24cm3 ): 6.33 [2] glycol manufacturer, Shenyang City glycol, Wei Wei Connaught Chemical provided by Qingdao Sino Chemical Company.
