METHOD FOR PRODUCING ALPHA-METHYLSTYRENE FROM CUMENE Russian patent published in 2017 - IPC C07C1/20 C07C15/46 C07C7/20 C07C7/04 

Abstract RU 2619117 C2

FIELD: chemistry.

SUBSTANCE: invention relates to two versions of the method for monitoring the non-volatile compounds formation in the production of alpha-methylstyrene. One version of the method comprises feeding the first composition to the distillation column, wherein said first composition contains acetone, phenol, cumene and alpha-methylstyrene; cleaning the first composition in the distillation column to obtain the second composition comprising at least 1 wt % of alpha-methylstyrene and at least one organic acid, wherein the weight percent of alpha-methylstyrene in the second composition is higher than in the first composition; and adding a certain amount of amine into the second composition.

EFFECT: method allows to regulate the formation of non-volatile compounds in the production process of alpha-methylstyrene and cumene.
