摘　　要：以α-萘乙酸和甲醇为原料,以硫酸铁为催化剂,通过酯化反应合成了植物生长调节剂萘乙酸甲酯,并通过正交设计讨论了醇酸比、催化剂用量、反应时间等因素对酯化产率的影响.在n(甲醇) : n(α-萘乙酸) = 20、催化剂用量为α-萘乙酸质量的7%、反应时间为2.0 h、酯化温度65～69℃的最佳反应工艺条件下,产物产率为95.8%.Using ferric sulfate as a cheap esterification catalyst, methyl a-naphthylacetate, an important regulator of plant growth, is synthesized from a-naphthylacetic acid and methanol. Through orthogonal test, the factors influencing on the reaction yield are discussed. Under the optimum reaction conditions, molar ratio of methanol to a-naphthylacetic acid 20, mass ratio of catalyst to a-naphthylacetic acid 7%, reaction time 2h, the highest yield is 95.8%.
