Abstract Polymer material preparation, catalyst preparation, material characterization and orthogonal experiment are introduced into chemical engineering experiments through esterification distillation of butyl citrate. (1) Through the preparation of polyaniline, students can understand the polymer polymerization experiment, broaden the scope of knowledge, and integrate the local industrial needs in the classroom. (2) Students can understand the preparation method of the catalyst, characterize and analyze the polymer materials and catalysts, master the application of instrumental analysis in catalyst preparation, and enhance the comprehensive experimental ability. (3) The orthogonal experiment is used to explore the best experimental conditions of esterification distillation experiment. (4) Butyl citrate esterification is used instead of ethyl acetate esterification to update the experimental content and meet the needs of the new development of new materials. This experiment can effectively connect the chemical engineering experiment with the local industrial needs and the cultivation of postgraduates’ scientific research ability. Through this experiment, students can apply book knowledge to practical application, increase their sense of acquisition,and improve innovative ability and comprehensive quality.
