摘　　要：以铌酸作催化剂,环己烷为带水剂,用丙酸和苯甲醇直接合成了丙酸苄酯。考察了催化剂用量、苯甲醇与丙酸物质的量比、反应时间和带水剂环己烷用量等因素对丙酸苄酯收率的影响。在最佳反应条件下,丙酸苄酯的收率可达87·9%。Using niobic acid as catalyst,cyclohexane as dehydrant, benzyl propionate was synthesized based on propionic acid and benzyl alcohol. The factors influencing on the yield of benzyl propionate, such as the dosage of catalyst, molar ratio of benzyl alcohol to propionic acid, reaction time and the amount of cyclohexane and so on, were investigated. Under the optimum reaction conditions, the yield of benzyl propionate could reach 87.9%.
