摘　　要：以棕榈酸、异辛醇(2-乙基己醇)为原料、对甲基苯磺酸为催化剂直接合成棕榈酸异辛酯。考察了反应温度、催化剂用量、反应时间及带水剂用量对酯化反应的影响,确定了合成棕榈酸异辛酯的优化反应条件∶催化剂用量为0.15wt.%,反应回流分水2.5h,带水剂环己烷20mL,反应温度120～140℃,收率达89.7%。Synthesis technology of iso-octyl palmitate with palmitic acid and iso-octanol （2-ethyl hexylaleohol）, using p -methyl-benzenesulfonie acid as catalyst, was described. The effects of the reaction temperature, amount of catalyst, reaction time and the amount of the dewatering reagent on the yield of esterifieation were investigated. The yield was 89.7% when the molar ratio of alcohol to acid was 1.5：1, weight percent of catalyst was 0.15%, temperature was 120-140℃, eyelohexane was 20mL and reaction time was 2.5h.
