Chinese name: 1,2-propanediol; 1,2-dihydroxy propane; propylene glycol; α- glycol [1] English name: 1,2-Propanediol; 1,2-Dihydroxypropane; α-Propylene glycol; Propylene glycol English Alias : (+/-) - 1-Glycerol, polymer-supported; ethane-1,2-diol - prop-1-ene (1: 1) Molecular formula: CH2OHCHOHCH3 (C3H8O2) EINECS: 200-338-01,2- glycol CAS: 57-55-6 Safety phrases: Avoid contact with skin and eyes with water, ethanol and various organic solvents. Propylene glycol can be used as the raw material of unsaturated polyester resins. In cosmetics, toothpaste and soap with glycerin or sorbitol can be used with a wetting agent. Humidity is used in hair dye, hair leveling agent propylene glycol manufacturer, also used as an antifreeze, is also used cellophane, plasticizers and pharmaceutical industries. The late 1980s, China only Shanghai, Shenyang and other places have several sets of mini-morpholino industrial grade propylene production plant, and belong to diethanolamine as raw acid dehydration process route of the old, high cost and low cost. 90 years later, the country has a number of research institutes to develop catalytic ammonia solution diethylene glycol cyclization process in which: ① FRIPP chemical plant in Liaoning Province, Qingyuan 500t / a industrial scale-up, to be successful. ② Beijing Research Institute of Petroleum in the low pressure range and a continuous flow fixed-bed reactor, the conduct of diethylene glycol catalyzed cyclization synthesis of ammonia solution of propylene glycol imported, and its development of synthetic catalysts used Pingdu Chemical Plant production. ③ Nanjing Chemical Plant use diethylene glycol pressure catalytic synthesis of morpholino, is a national initiative. ④ Nanjing Jinling Petrochemical Company fertilizer plant contract Bleach 500 tons / year plant, put into operation in 1993. 500 tons / year plant ⑤ Liaoyuan footage plant utilization Jilin Chemical Company Institute diethylene glycol ammoniated synthesis morpholine. The technology has been built three sets of 500 tons / year plant, tons of products consume less than 1.7 tons of diethylene glycol, product quality has reached the advanced level, and in line with BASF company standards. Diethylene glycol as the raw material of new production plant in Shandong, Jilin, Anhui, Jiangsu and other places have been put into operation, but many small and medium-propanediol, the maximum size of 800 tons / year, some the size of only 100 tons / year, production technology and product quality is uneven.
