Login EINECS No.: 203-872-2 InChI = 1 / C4H10O3 / c5-1-3-7-4-2-6 / h5-6H diethylene glycol quotes, 1-4H2 structural formula: diethylene glycol structure materialized data: Relative Density: 1.1164 (20 ℃) ??pure freezing point: -l0.45 ℃ Boiling point: 244.8 ℃ Melting point: -10.45 ℃ Flash Point 143 ℃ (opening) 124 ℃ (closed) Flash point: 351.9 ℃ refractive index: 1.4472 (20 ℃ ) Viscosity: (25 ℃) 30mPa · s morpholine production, mainly taken to diethylene glycol and ammonia as raw materials. Under the action of a hydrogenation catalyst, while completing aminolysis and dehydration reaction shelf diethylene glycol, obtained by distillation of crude morpholino purity> 99.5% (by weight) of fine morpholine. Depending on the operating pressure of the different uses of diethylene glycol, the technology into high-pressure liquid method, low vapor pressure contact method and three gas-phase synthesis. Since 1980 the United States Air Products and Chemicals, Inc. developed a new low-voltage technology, currently there are a number of companies have tons morpholino plant. And Japan and other countries are competing for the development, but morpholino prices remain high. Price of diethylene glycol, diethylene glycol, Weihai, Xiang Xiang dry chemical provided by the Jinan Chemical Co. dry. Jinan Cheung Dry Chemical Co.
