摘要
以异丁醇和甲酸为原料在常压下制三甲基乙酸，反应最佳条件为：ｎ（异丁醇）∶ｎ（甲酸）＝０．７５，ｎ（催化剂）∶ｎ（异丁醇）＝６．６，反应温度５５℃，滴加和搅拌时间分别为２５ｍｉｎ和７５ｍｉｎ；适当调节催化剂硫酸的量，收率可达８４．０％。
Optimum conditions for preparing trimethylacetic acid from iso butanol and formic acid as follows: n (iso butanol)∶ n (formic acid)=0 75, n (catalyst)∶ n (iso butanol)=6 6,reaction temperature is 55℃,times for dropping in and stirring are 25 min and 75 min,respectively.Yield of final product can be reached 84 0% when suitable amount of sulfuric acid is added.
