摘　　要：研究了以邻氯苄氯和乙酸钠为主要原料,在相转移催化剂的存在下发生酯化反应生成乙酸邻氯苄酯,然后用30%的氢氧化钠水解,制备邻氯苄醇。同时考察了催化剂、反应物的配比和搅拌速率等因素对邻氯苄醇收率的影响。The preparation of o - Chlorobenzylalcohol by hydrolysis from o - chlorobenzylchloride was studied. In the presence of PTC, o- chlorobenzylchloride reacts with sodium acetate tO produte ester, and then hydrolyze with 30 % NaoH to yield o- chlorobenzylalcohol. The effects of PTC, the ratio of o - chlorobenzylchlohde to sodium acetate and strring rate on the yield of o - Chlorobenzylalcohol were also investigated.
