Novel catalyst for synthesizing tertiary-butyl substituted benzene phenols and its preparation process

Abstract

The invention is a new catalyst for synthesizing tert-butyl to replace phenol and the process, belongs to the synthesizing method for tert-butyl to replace phenol and relative solid acid catalyst, which refers to crystal silicon aluminum acid salt catalyst and the process. the catalyst is made up mainly by micropore aluminosilicate, and loads one to three kinds of elements of boracium, magnesium, aluminum, phosphorus, calcium, titanium, zinc, molybdenum as active components, the process is convenient, the activity and the selectivity are high, can be sued repeatedly; the reaction uses moderate operation condition and continuous flow method, the tert-butyl replaced phenol can be produced by putting phenols and alkylation agent through the catalyst bed; the environment of the process is friendly, the side product is little, the process is simple.

Description

technical field

[0001] The invention belongs to the field of a new method for synthesizing tert-butyl-substituted phenol and related solid acid catalysts, and relates to a catalyst based on crystalline aluminosilicate, a preparation method thereof and a process for synthesizing the phenols by catalytic alkylation reaction. The catalyst is mainly composed of microporous crystalline aluminosilicate, which is prepared after physical and chemical treatment; the catalytic alkylation reaction process adopts relatively mild operating conditions and continuous flow mode, and phenols and alkylating reagents Through the catalyst bed, selectively catalyze the reaction of phenols and alkylating reagents to synthesize tert-butyl substituted phenol in one step. technical background

[0002] Tert-butyl substituted phenol is an important industrial raw material and organic synthesis intermediate, widely used in synthetic resin, rubber, dye, paint, medicine, pesticide and other industries, w...
