METHOD OF PRODUCING α-METHYLSUBSTITUTED CARBONYL COMPOUNDS Russian patent published in 2016 - IPC C07C45/71 C07C49/04 C07C49/10 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing α-methylsubstituted carbonyl compounds of gthe eneral formula R¹-CO-CR³(CH₃)-R², where: R¹ and R²-hydrogen H or a linear or branched alkyl radical containing 1 to 12 carbon atoms, R³-H or CH₃ radical, which are feedstock for producing a number of chemical products and drugs, are used as solvents and can be used as a base for producing high-octane motor fuel components. Method involves conversion of initial gas-vapour mixture of carbonyl compound selected from compounds of general formula R⁴-CO-CHR⁵-R⁶, where: R⁴ and R⁶-H or a linear or branched alkyl radical containing 1 to 9 carbon atoms, R⁵-H or CH₃ radical, and methanol using copper-containing catalyst when introducing in initial reaction mix of hydrogen.

EFFECT: proposed method allows to increase the catalyst interregeneration runtime in several times, and consequently, the amount of product obtained per unit volume of the reactor.
