Main: Dow propylene glycol, SKC propylene acrolein hydration hydrogenated 1,3-PDO process patent is the largest German company Degussa, followed by German company Hoechst. Degussa company acrolein as a raw material 1,3-PDO major industrialized line production steps are: (1) acrolein hydration of 3-hydroxy propionaldehyde; (2) 3-hydroxypropionaldehyde catalytic hydrogenation of 1, 3-PDO. Experts believe that the production technology is relatively mature, low cost, wide range of raw materials is relatively inexpensive. But there are low selectivity of the catalyst, propylene glycol product separation process is complex packaging, poor quality pharmaceutical grade propylene glycol, severe pollution, and acrolein explosive, difficult storage, production and more dangerous defects, so the higher cost of production . The difficulty of this process is that the selection of the catalyst, the process is currently still in the pilot stage, the technology needs to be improved pharmaceutical grade propylene glycol | Jan-Chemical (certified) | Zhuhai glycol provided by Jan-Chemical Co., Ltd. in Guangzhou.
