研究了苯甲醇高收率的制备方法;在相转移催化剂和助催化剂羧酸盐的存在下,氯化苄用氢氧化钠水溶液水解得到苯甲醇,水解母液可循环使用;考察了羧酸盐的用量、pH、氯化苄与水初始投料比,搅拌速度及母液循环套用次数等因素对苯甲醇收率的影响,苯甲醇最高收率96.0％.“,”This paper studied the preparation technology of benzylalcohol form benzylchliride in high yield. In the presence of PTC and cocatalyst, benzylchloride react with 30% NaoH to yeild benzlalcohol, the water containing PTC and sodium carboxylate may be reused. The effect of the amount of cocatalyst.pH.the ratio of benzychloride to raw materials.stirring speed and the recycle - used times of the hydrolysis mother liquor on the yield of benzylalcohol are also investigated. The highest yield the benzylalcohol is 96%
