摘　　要：通过水热方法自制了一种ZSM-5分子筛催化剂,用于从松香和甘油催化合成松香甘油酯。通过合成松香甘油酯实验评价和采用XRD、SEM、N_2-吸脱附和NH_3-TPD等分析手段进行表征,对自制催化剂与市购的ZSM-5分子筛催化剂的催化性能和结构特点进行进行了比较。结果表明,与购买的ZSM-5分子筛相比,自制ZSM-5分子筛作催化剂具有更高的比表面积和中孔体积,合成松香甘油酯所得酯化率较高,酸值较低,稳定性高。A ZSM-5 zeolite was synthesized by hydrothermal crystallization method and used for preparation of rosin glyceride from rosin and glycerin. The catalytic performance and structure of the prepared and purchased ZSM-5 zeolites were compared by the synthesizing experiments of rosin glyceride and characterizing the structure of zeolites using XRD, SEM, N2-adsorption desorption and NH3-TPD. The results showed that compared to the purchased ZSM-5 zeolite, the synthesized ZSM-5 zeolite had higher specific surface area and mesopore volume, exhibiting higher esterification rate, lower product acid value and better stability.
