丙二醇苯醚的工业合成

Synthesis of Propylene Glycol Phenyl Ether

以苯酚和环氧丙烷为原料合成了丙二醇苯醚。当有机碱A和无机碱A的重量比为1∶1时,催化剂的催化活性最好,产品的选择性可达97.5%,产品色号为50号。由于压力对反应的影响比较小,反应应尽量在接近常压的条件下进行。通过实验选定静态混合器作为反应器。

Propylene glycol phenyl ether is synthesized based on phenol and propylene epoxide as raw materials. The selectivity of propylene glycol phenyl ether reaches to 97.5% with chroma of 50 when the weight ratio of organic base to inorganic base is 1： 1. Since the reaction pressure exerts a little impact on the reaction, the reaction can be carried out under near normal pressure. The results show that the static mixer is most suitable for the process.
