摘要
以纳米复合钨硅杂多酸为催化剂,异戊酸和异戊醇为原料,通过酯化反应合成苹果油,对酯化反应的影响因素进行了研究,结果表明,在醇酸物质的量比为1.4∶1,催化剂用量5%,反应时间1.5h的条件下,酯化率可达98.6%。
Isoamyl isovalerate was synthesized through esterification reaction by using isovaleric acid and isoamyl alcohol as raw materials and nano-H4SiW12O40SiO2 as catalyst, the influencing factors in the reaction were studied, and the results showed that the csterification rate could reach 98.6 % under the conditions of the ratio of alcohol-acid 1.4：1, the use level of catalyst 5 %, and the reaction time 1.5 h.
