METHOD FOR DECOMPOSITION OF ISOPROPYLBENZENE HYDROPEROXIDE TO PRODUCE DIMETHYLPHENYLCARBINOL Russian patent published in 2021 - IPC C07C29/00 C07C33/20

Abstract RU 2750718 C1

FIELD: chemical industry

SUBSTANCE: invention relates to a method for the decomposition of isopropylbenzene hydroperoxide to produce dimethylphenylcarbinol, which is a raw material for the production of a-methylstyrene, a valuable monomer for the production of synthetic rubbers, latexes, and various water-resistant sealants. The method is applied at a temperature of 130°C in the presence of a catalyst in the amount of 0.005-0.01 mol/l, being 2-ethylhexanoate of potassium.

EFFECT: method makes it possible to increase the conversion of isopropylbenzene hydroperoxide to 40%, with selectivity for dimethylphenylcarbinol of 89-82%.
