摘　　要：在微波辐射下,用活性炭磺化制得固体磺化炭作为催化剂,由乙酸和异戊醇合成乙酸异戊酯。对乙酸与异戊醇酯化反应条件进行优化,优化条件是:酸醇摩尔比为1.8:1,反应温度为200℃,反应时间为20 min,催化剂用量为实际反应的乙酸质量的8%.乙酸的酯化率达85.51%.产物经过红外光谱表征。Isoamyl acetate was synthesized from acetic acid and isoamyl alcohol with solid sulfonic acid sulfonated ac-tivated carbon as catalyst under microwave irradiation. The effect of factors on the yield was studied and the optimum reac-tion conditions were found. They were as follows： molar ratio of acetic acid to isoamyl alcohol was 1.8 ： 1, reaction tem-perature 200 ℃, reaction time 20 min, and the dosage of the catalyst was 8% of the practical acetic acid quality. Under the conditions, the yield was 85.51%. The product was characterized by IR.
