硫酸氢钠能代替硫酸作为酯化作用催化剂．探讨了一水硫酸氢钠为催化剂，由１－萘乙酸和甲醇酯化合成１－萘乙酸甲酯的优化条件．当１－萘乙酸、甲醇和硫酸氢钠的质量比为１：３２：０．８，回流反应７小时，酯收率可达９６％．
Sodium bisulfate can replace sulfuric acid as esterification catalyst. The optimal conditions for the synthesis of methyl 1-naphthylacetate from 1-naphthaleneacetic acid and methanol by sodium bisulfate monohydrate as catalyst were discussed. When the mass ratio of 1-naphthalene acetic acid, methanol and sodium bisulfate was 1: 32: 0.8, the reaction was refluxed for 7 hours, the yield of ester reached 96%.
