METHOD FOR OBTAINING CUMENE Russian patent published in 2023 - IPC C07C1/22 C07C1/24 C07C15/85 C07C33/20 C07C5/03 

Abstract RU 2809251 C2

FIELD: organic synthesis.

SUBSTANCE: invention is related to a method for producing cumene by subjecting cumyl alcohol to a hydrocracking or dehydration reaction and subsequent hydrogenation reaction to obtain cumene. The method includes the following stages: (A) feeding a liquid containing cumene into a reactor loaded with catalyst; and (B) supplying hydrogen and a liquid containing cumyl alcohol to the reactor after step (A), wherein in the case where the cumyl alcohol is subjected to a hydrocracking reaction to produce cumene, the catalyst is not a catalyst containing copper.

EFFECT: provision of a method for producing cumene, in which the amount of by-product isopropylcyclohexane produced is small.
