【摘要】 研究了选用大孔强酸性阳离子交换树脂作催化剂,在不同条件下催化合成乳酸甲酯。实验结果表明:在催化剂作用下,甲醇与乳酸摩尔比为2:1,反应温度为80℃,流速为200g.h-1,酯化收率达85.36%。更多还原

【Abstract】 Synthesis of methyl lactate on the cation exchange resin was studied under different conditions.After a series of experiments,the optimal conditions of esterification under the catalyst were achieved:molar ratio of methanol to lactic acid as 2:1,reaction temperature was 80 ℃,velocity of flow was 200 g·h-1.The yield of esterification could reach 85.36%.更多还原
