α-蒎烯择形催化异构研究

STUDY ON CATALYTIC SHAPE SELECTIVE ISOMERIZATION OF α- PINENE

用化学气相沉积法修饰 13X分子筛和丝光沸石制备择形催化剂 ,利用吸附法和甲苯歧化模型反应测定了XC系列和HMC系列催化剂的孔径范围。并用上述催化剂催化α 蒎烯异构化反应 ,根据反应结果初步推测了α 蒎烯、异松油烯和烯的有效分子径范围分别为 0 68nm以上、0 68nm左右和 0 5

In this study, molecular sieve 13X and mordenit were modified by chemical vapor deposition method to prepare shape selective catalyst, and pore diameters of the catalyst were measured by adsorption and toluene disproportionation methods. It was inferred from the results of α piene isomerization catalyzed by these shape selective catalysts, that the kinetic diameters of α pinene, terpinolene and limonene are approximately>0.68 nm, 0.68 nm and 0.58 nm, respectively.
