Abstract

The invention relates to a bisamide bond long carbon chain organosilane quaternary ammonium compound and preparation and application thereof. A structural formula of the compound is shown in the specification, wherein m is any integer from 1-18, n is any integer from 1-5, X is one of Cl<->, Br<-> and I<->. The preparation is as follows: adding N-methylimino diacetic acid, aliphatic amine, 1-hydroxy benzotriazole HOBT, carbodiimide EDCI and triethylamine in a solvent, stirring at room temperature to stay overnight, and purifying to obtain a bisamide chain intermediate; mixing the bisamide chain intermediate and haloalkyl trimethoxy silane, reacting, cooling, and washing to obtain the compound. The compound is applied to the preparation of a mesoporous ZSM-5 molecular sieve. A hierarchical porous zeolite molecular sieve prepared by the invention is capable of obviously improving the pore volume and specific surface area of the zeolite molecular sieve, and the aperture and pore volume of the hierarchical pores of the molecular sieve can be effectively regulated through the changing of carbon atom number of the diacyl aliphatic chain.

Description

technical field [0001] The invention belongs to the field of quaternary ammonium salt compounds and their preparation and application, in particular to a double amide bond long carbon chain organic silane quaternary ammonium salt compound and its preparation and application. Background technique [0002] Zeolite molecular sieves are widely used as catalysts in petrochemical and fine chemical industries. Because of their unique adsorption and separation functions, they are also widely used in engineering and technical fields such as ion exchange, adsorption and separation, and environmental protection. However, traditional zeolite molecular sieves are mostly microporous (pore size less than 2nm), which is difficult to catalyze chemical reactions of macromolecules, so the application of microporous zeolite molecular sieves in the field of macromolecular catalysis is limited. Especially in today's global petroleum resources are becoming less and less, and the content of heavy o...
