HYDROALKYLATION OF BENZENE WITH ACETONE USING BIFUNCTIONAL CATALYSTS

Abstract

Currently, cumene (isopropylbenzene) is obtained by alkylation of benzene with propylene. The production of Kumol is more than 8 million. 600 thousand tons in Russia. Cumene is used in the production of phenol. As the production of phenol increases every year, the production of cumene also increases. The main goal here is the hydroalkylation of benzene with acetone in the presence of a solid catalyst and the development of a new method for obtaining cumene. It is of great importance to develop new highly profitable and environmentally friendly methods for acetone processing. Therefore, it is most profitable to obtain cumene by alkylation of acetone with benzene. The main issue is the acquisition of cumene and diisopropylbenzenes. For this purpose, a high-quality catalyst was developed that provides 83% selectivity of cumene in 97% conversion of acetone connecting copper-containing zeolite components.
