Synthesis of Hierarchical Micro-mesoporous ZSM-5 Zeolite and its Catalytic Activity in Benzylation of Mesitylene

Hierarchical micro-mesoporous ZSM-5 (MFI type) zeolite was synthesized by using corn plant stem pith powder from agricultural waste as hard template under simple hydrothermal method. The additional porosity generated this into the zeolites precursor gel yielded hierarchical (C-ZSM-5). Conventional micro porous (ConvZSM-5) also prepared same procedure without adding to compare catalytic performances. C-ZSM-5 exhibited 89% conversion, much greater than ConvZSM-5 (33%). Selectivity in formation of 2-Benzyl-1, 3, 5-trimethylbenzene, benzylation with (70%) is more two times (32%). This can be used a test reaction evidence nature material. better selectivity and benzyl alcohol conversion due presence pores strong acidy C-ZSM-5.The product formed above separated further confirmed 1HNMR 13CNMR. Even after consecutive recycles every month for three months, desired products had not been affected. present catalyst improved stability zeolites. Hence could very useful industrially important reactions.
