Problems solved by technology

However, the size of the mesoporous material SBA-16 spheres reported in the literature is at the millimeter level, and the surface of the pore wall of the mesoporous material SBA-16 has only silicon hydroxyl groups, resulting in low chemical reactivity, which greatly limits its practical application value.

Abstract

The invention relates to the technical field of catalyst synthesis, in particular to a zinc trifluoromethanesulfonate-loaded spherical mesoporous material, and a preparation method and application thereof. The mesoporous material serves as a catalyst which is used for a reaction process for preparing cyclohexanone-1,2-propylene glycol from cyclohexanone and 1,2-propylene glycol. The mesoporous material has the advantages of high conversion rate of a reactant after a catalytic reaction, a small number of side reactions, high product purity, high conversion rate after repeated use and environmental friendliness.

Description

technical field [0001] The invention relates to the technical field of catalytic synthesis, in particular to a mesoporous material containing zinc sulfonate of aromatic hydrocarbons and a preparation method and application thereof. Background technique [0002] Due to the high surface area and pore volume of mesoporous materials (Kresge, C.T.; Leonowicz, M.E.; Roth, W.J.; Vartuli, J.C.; Beck, J.S. Nature 1992, 359, 710.), easy-to-modulate regular nanopores, abundant and Easy-to-design surface groups, as well as tunable macroscopic morphologies (such as membranes, fibers, spheres, etc.), have shown unique development potential in the fields of protein separation, biosensors, catalysis, optical devices, adsorption, and microelectronics (Zhao , D.; Yang, P.; Huo, Q.; Chmelka, B.F.; Stucky, G.D. Curr. Opin. Solid State Mater. Sci. 1998, 3, 111.3 Mann, S.; Asefa, T.; MacLachan, M.J.; Coombs, N.; Ozin, G.A. Nature 1999, 402, 867. MacLachlan, M.J.; Ginzburg, M.; Coombs, N.; Raju, ...
