【Abstract】 Propanediol phenyl ether was synthesized from phenol and propylene oxide(PO)in the presence of a series of solid-based catalysts derived from hydrotalcite-like compounds.The effects of the composition and structure of the catalysts,and the reaction conditions on the synthesis of propanediol phenyl ether were studied.The optimum reaction conditions were as follows:the amount of ZnMgAl catalyst was 1.1%,the molar ratio of C6H5OH to PO was 1∶1,reaction temperature was 413 K,and reaction time was 5 h.The conversion of PO was 97.2%,the selectivity of propanediol phenyl ether was 93.4%.更多还原
