摘　　要：在钨磷酸铝的存在下,由乳酸和异戊醇合成了乳酸异戊酯,当乳酸与异戊醇摩尔比为1∶4,钨磷酸铝用量为0.4g,在115℃加热回流3h时,酯收率达96%。Isopentyl lactate was synthesized from lactic acid and isopentyl alcohol in the presence of aluminium tungstophosphate. The yield of the ester could reach 96% in the condition of the mole ratio of lactic acid to isopentyl alcohol is 1∶4, aluminium tungstophosphate is 0.4 g, heating temperature 115 ℃ and refluxing time 3 h.
