| 摘 要： | 以对羟基苯甲酸与正丁醇为原料，对甲苯磺酸为催化剂，微波辐射催化合成了对羟基苯甲酸正丁酯。优化了合成条件，结果表明：当正丁醇为0．4mol，对羟基苯甲酸为0．1mol，催化剂为0．80g，微波辐射的功率为600W，反应温度为120℃，时间为12min时，反应产率达92．8％。产品经过熔点测定仪和红外光谱仪表征，证实与目标产物完全一致。

| Abstract: | N-Butyl-p-Hydroxybenzoates were synthesizd with p- hydroxybenzoic acid and n-butyl alcohol as raw material and p-toluene sulfonic acid as catalyst under microwave irradiation. The yield of ester was 95.4 % under optimal reaction conditions which n-butyl alcohol was 0.4 tool, p-hydroxybenzonic acid was 0.1 tool, p-toluene sulfonic acid was 0.8 g, irradiation power was 600 W, irradiation temperature was 110 ℃, irradiation time was 10 min. The product was consistent with the target one characterized by IR and melting point determination. |
