METHOD OF HYDROGENATING ALPHA, BETA-UNSATURATED KETONES Russian patent published in 2014 - IPC C07C49/213 C07C49/657 C07C45/62

Abstract RU 2529032 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method of hydrogenating α,β-unsaturated ketones of general formula , where R₁, R₂=H or R₁-R₂=-(CH₂)₃-, which includes hydrogenating benzal alkanone with hydrogen gas in a solvent medium in the presence of a catalyst. The benzal alkanone used is benzalacetone or benzalcyclohexanone, and the catalyst used is colloidal nickel particles obtained by reducing nickel (II) chloride with lithium aluminium hydride, and the process is carried out at atmospheric pressure of hydrogen in a tetrahydrofuran medium at 55-60°C.

EFFECT: invention enables to obtain saturated ketones with high output using a simple method.
