“…Studies on pore structure adjustment by solvent-free method of MOR was still rare. In order to enhance the mass transfer efficiency and delay the deactivation process during carbonylation reaction over MOR, 10,11 one of the most direct and effective way was to introduce mesoporous structure into the zeolite. 12–14 To determine a suitable soft template agent for the synthesis of hierarchical MOR by solvent-free method, three typical soft templates were picked out and used in the synthesis process.…”

Different solid superacid sulfated ZrO 2 (SO 4 2-/ZrO 2 ) samples were successfully prepared by conventional and ultrasonic assisted chemical precipitation process, and then they were characterized by XRD, FT-IR, TGA, BET, NH 3 -TPD and Py-FT-IR. The results indicate that the acidity and surface area of sulfated sample can be increased by using ultrasonic. Furthermore, this ultrasonic-assisted catalyst was used for the chlorobenzene nitration using NO 2 as nitrating agent. The catalyst shows excellent catalytic activity and reusability for the nitration of chlorobenzene giving high para selectivity. Furthermore, the reaction mechanism was proposed by combination of experimental results and theoretical calculations. The present work provides an easy-to-implement, mild and environmentally friendly approach for the e cient preparation of valuable para-nitrochlorobenzene, which has extensive industrial application prospects.
