Document Type and Number:
Japanese Patent JP4507328
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a process for the production of benzyl alcohol with excellent operation stability. SOLUTION: Benzyl acetate, methanol, water and a basic catalyst are supplied to a reaction distillation column A and benzyl alcohol is produced by the catalytic reaction of benzyl acetate with methanol in the presence of the basic catalyst. A fractionation part for methyl acetate and methanol is placed above the feeding position (feeding stage) of benzyl acetate and a part of column top mixture is refluxed. The refluxing ratio X and the molar ratio Y of the supplied methanol to the supplied benzyl acetate is maintained to satisfy the formula, Y>=1.507+0.662/(X+0.444) (wherein, X>0).
