摘　　要：采用ＦｅＣｌ３·６Ｈ２Ｏ为催化剂，由α－萘乙酸和甲醇制得植物生长调节剂α－萘乙酸甲酯，在催化剂用量为酸的１３．５％（Ｗ）、醇酸物质量之比为２０：１、酯化时间为１．５ｈ、酯化温度６５～６９℃的最佳工艺条件下酯收率为９５．０％。Using FeCl3.6H2O as catalyst, methyl α- naphthal eneacetate is synthesize from α - naphthyl acetic acid and methanol. The highest yield of esterification can reach 95. 0%. The optimtum conditions are: the weight of the catalyst is 13. 5% of that of the acid; the mol ratio between the alcohol and the acid is 20:1; the reaction temperature is 65-69℃ and the time of esterification is 1. 5 hours.
