分别以固体酸CsnH3 -nPW12 O40 和SO2 -4/ZrO2 为催化剂研究了正己醇酯化反应。考察了磷钨酸铯盐中铯含量和酸强度、SO2 -4/ZrO2 中酸浓度和酸强度以及不同有机酸对正己醇酯化反应的影响。结果表明 ,正己醇的酯化反应活性随着固体酸的酸强度和比表面积的增加而增加。利用IR、XRD、空气吸附法等检测手段分别对催化剂进行了表征。
Esterification of n-hexanol with solid acids CsnH3-nPW12 O40 and SO2-4 / ZrO2 as catalysts respectively. The effects of cesium content and acid strength in cesium phosphotungstate, acid concentration and acid strength in SO2-4 / ZrO2 and esterification of n-hexanol with different organic acids were investigated. The results showed that the esterification reactivity of n-hexanol increased with the increase of acid strength and specific surface area of solid acid. The catalysts were characterized by means of IR, XRD and air adsorption.
