以乙酸和苄醇为原料，用固体催化剂铌酸催化合成了乙酸苄酯，发现在乙酸与苄醇的摩尔比为4：1，适量催化剂和带水剂存在下回流反应270 min，产物收率可达67.296，而且催化剂容易回收重复使用。
以乙痠和芐醇為原料，用固體催化劑鈮痠催化閤成瞭乙痠芐酯，髮現在乙痠與芐醇的摩爾比為4：1，適量催化劑和帶水劑存在下迴流反應270 min，產物收率可達67.296，而且催化劑容易迴收重複使用。

Benzyl acetate was synthesized with acetic acid and benzyl alcohol as raw materials and a new solid niobic acid as esterification catalyst. The results showed that the yield reached 67.2％ when the mole ratio of acetic acid and benzyl alcohol was 4, reaction time was 270 min in the presence of proper amount of catalyst and cyclohexane. The catalyst could be separated easily and reused for times.
