摘要
Abstract
Solid superacid catalyst SO42−/Kaolin was prepared by twice impregnation-roasting,and the synthesis mechanism of conversion of lactose to levulinic acid was studied. The effects of technological condition , such as catalyst calcination temperature , catalyst dosage , lactose concentration,reaction temperature,reaction time on the relative yield of levulinic acid were investigated and orthogonal experiment was used to determine the optimum conditions. The result showed that the highest relative yield of levulinic acid was 79.13% under the optimal conditions of catalyst calcination temperature 650 ℃,lactose concentration 5 g/L,reaction temperature 200 ℃, reaction time 120 min,catalyst dosage 15%of lactose.关键词
