Embodiment 1

[0020] 1). Polymerization reaction

[0021] The well-known macroporous styrene-based ion-exchange resin polymerization production process is selected in the industry, and the cross-linking degree is controlled to 15%, and the porosity is 30%. In addition, hexafluorobutyl acrylate, which accounts for 0.1% of the monomer mass percentage, and 0.1% The phenol participates in the polymerization, and then the finished product is obtained through sulfonation and other processes. Designated as KRB-1

Abstract

The invention discloses a resin catalyst applied to preparation of phenol through decomposition of cumene hydroperoxide (CHP) and a preparation method for the resin catalyst. The preparation method comprises the following steps of: by a macroporous styrene ion exchange resin aggregation production process, adding a (methyl) crylic acid halothane-based ester monomer and the phenol, aggregating, sulfonating, and thus obtaining the resin catalyst. The prepared catalyst is high in oxidation resistance and mechanical strength, has long service life, can be widely applied in production, and has an extremely good application prospect in the field of preparation of the phenol through a CHP decomposition reaction.

Description

technical field [0001] The invention relates to a resin catalyst and a preparation method thereof, in particular to a resin catalyst used in decomposing cumene hydroperoxide to prepare phenol and a preparation method thereof. Background technique [0002] At present, more than 90% of the phenol in the world is produced by the cumene method. The method mainly includes three reactions: alkylation reaction, oxidation reaction and decomposition reaction. For the decomposition reaction of cumene hydroperoxide (CHP), most of them use the traditional concentrated sulfuric acid catalyst. The reaction is violent, difficult to operate, with many by-products, difficult product separation, serious equipment corrosion, and the sulfuric acid produced by neutralizing sulfuric acid with alkali Sodium is easy to cause fouling of the reboiler of the rectification system. When dealing with scaling, more phenolic sewage is produced. polluted environment. Therefore, it is necessary to find a...
