Abstract:Propylene glycol phenyl ether was synthesized by using phenol and epoxy propane as raw materials, and Lewis base named triphenylphosphine as catalyst. The effects of different process conditions on the reaction selectivity of propylene glycol phenyl ether was compared, the optimum process conditions were obtained, respectively, the molar ratio of phenol and epoxy propane was 1.00∶1.03, the catalyst dosage was 2.0‰ and the reaction temperature was 120 ℃. Under optimized conditions, the selectivity reached 98.59%, realizing the industrial production of domestic high-selective propylene glycol benzene ether. |
Key words:propylene glycol phenyl ether; selectivity; synthesis; catalyst; industrial production |
