PROCESS FOR THE PREPARATION OF BENZYL ALCOHOL

摘要

Process for the preparation of benzyl alcohol via hydrolysis of a benzyl ester with water in the liquid phase, the hydrolysis being carried out in the absence of a strong acid and a base at a temperature between 40° C. and 320° C. The benzyl ester to be hydrolyzed can be chosen from the group comprising benzyl formiate, benzyl propionate, benzyl acetate and benzyl benzoate. A weak acid may optionally be added to the reaction mixture to be hydrolyzed. After the hydrolysis the reaction mixture is preferably cooled to a temperature between 80° C. and 180° C. so that a phase separation takes place. Both the organic phase and the aqueous phase can be upgraded. As such, benzyl alcohol can be obtained with a high overall yield and a purity of more than 98%.
