摘　　要：以月桂酸和甲醇为原料,浓硫酸为催化剂,采用两步酯化法制备月桂酸甲酯。研究了催化剂质量分数、醇油质量比、反应温度、甲醇流速对反应产率的影响。实验结果表明,第一步酯化甲醇的质量百分数为80%,浓硫酸质量百分数为0.5%,反应温度65±2℃;第二步循环酯化通入甲醇的流速为1.5mL/min,反应温度100±5℃时,月桂酸甲酯化的转化率最高。In this paper,synthesis methyl was prepared from lauric acid and methanol by two-step esterification method,using concentrated sulfuric acid as catalyst.The dosage of catalyst,methanol and oil,reaction temperature,and flow velocity of methanol has been measured.The experiments show that the optimum experimental conditions have been determined.At the first step,the mass ratio of methanol is 80%,reaction temperature 65±2℃ and catalyst dosage 0.5%.At the second step,the flow velocity of methanol is 1.5mL/min and the experimental temperature is 100±5℃.
