AbstractMnSAPO-34 molecular sieves were synthesized by vapor-phase transport (VPT) method using triethylamine (Et3N) as a structure directing agent (SDA), and were characterized by XRD, BET, SEM, UV-Vis, FT-IR, and TO analyses. The influence of the zeolite crystallization conditions and the dry-gel composition were investigated. The results showed that the synthesis conditions had an effect on the crystalline phase. Pure MnSAPO-34 had been obtained when it was crystallized at 140 degrees C for 18 hours. The ratio of MnO/Al2O3 in the starting gel ranging from 0.1 to 0.2 resulted in pure MnSAPO-34 with a CHA topology. Beyond this scope, MnSAPO-5 with an AEI topology structure was obtained as an impurity substance. UV-Vis spectroscopy and FT-IR spectroscopy study indicated that manganese was incorporated into the framework of the molecular sieve. The catalytic performance of MnSAPO-34 molecular sieve was tested by ketalization reaction of 1, 2-propanediol with cyclohexanone. High yield of cyclohexanone-1, 2-propanediol ketal was obtained.; MnSAPO-34 molecular sieves were synthesized by vapor-phase transport (VPT) method using triethylamine (Et3N) as a structure directing agent (SDA), and were characterized by XRD, BET, SEM, UV-Vis, FT-IR, and TO analyses.
