摘　　要：制备了ZrO2/SO42-型固体超强酸催化剂,在该固体超强酸的催化作用下,由乳酸和异戊醇合成了乳酸异戊酯。探讨了焙烧温度、催化剂用量、反应时间和试剂摩尔比的影响,利用IR、质谱分析表征了乳酸异戊酯的结构。ZrO2/SO4^2- - solid superacid catalyst was prepared. Isopentyl lactate was synthesized from lactic acid and isopentyl alcohol in the presence of this solid superacid. The influence of calcination temperature , catalytic dosage, reaction time and molar ratio of reagents were studied. The structure of the Isopentyl lactate was characterized by IR and mass spectrometry.
