摘要：

Ethyl levulinate is a potential biomass-based platform compound, which has a wide application in chemical industry. The traditional methods for manufacturing ethyl levulinate are mainly in a batch reactor, which had a low efficiency, difficult in product separation and a long technological process. Therefore, a reactive distillation process in producing ethyl levulinate was proposed. Based on the results of pilot-scale experiments, the reactive distillation technological process was established using Aspen Plus simulation software, the key parameters, such as reflux ratio, feeding position, feed mole ratio and theoretical stage numbers were investigated, and the optimal configuration for the synthesis of ethyl levulinate using conventional reactive distillation technology was obtained. In order to obtain ethyl levulinate with a purity higher than 99.9%, the double column reactive distillation purification process and the reactive dividing-wall distillation process were further proposed, and through the comparison of product purity and energy consumption of these two processes, the effectiveness of reactive dividing-wall distillation process in producing ethyl levulinate was verified and its energy saving effect was demonstrated. © 2022, Chemical Industry Press Co., Ltd.
