硫酸氢钠能够代替硫酸作为酯化作用催化剂。在一水硫酸氢钠存在下,由正丁酸和异丁醇合成了丁酸异丁酯。在正丁酸、异丁醇和硫酸氢钠的物质的量比为4∶3∶0.07,回流分水60min,酯收率达99.3%,同时研究了催化剂的重复使用性能。
Sodium bisulfate can replace sulfuric acid as an esterification catalyst. Isobutyl butyrate was synthesized from n-butyric acid and isobutyl alcohol in the presence of sodium bisulfate monohydrate. The mass ratio of n-butyric acid, isobutyl alcohol and sodium bisulfate was 4: 3: 0.07, refluxing for 60 min and the yield of ester reached 99.3%. The reusability of the catalyst was also studied.
