摘要
在强酸性阳离子交换树脂存在下 ,由乳酸和异戊醇合成了乳酸异戊脂。当乳酸和异戊醇的物质比为 1∶2 (mol/mol) ,强酸性阳离子交换树脂的用量 1.5g ,回流分水 60min ,酯收率达 92 %。同时 ,研究了催化剂的重复使用性能。
Isopentyl lactate was synthesized from lactic acid and isopentyl alcohol in the presence of strongly acidic cationic exchange resin. The yield of the ester can reach 92% in the condition of lactic acid and isopentyl alcohol 1∶2( W/W ), strongly acidic cationic exchange resin 1.5g, refluxing and water segrating for 60min. The reuseability of the catalyst was studied.
