METHOD OF PRODUCING 5-METHYL-3-HEPTANONE AND POLYFUNCTIONAL CATALYST Russian patent published in 2020 - IPC C07C45/45 C07C49/04 B01J21/18 B01J23/44

Abstract RU 2739257 C2

FIELD: chemistry.

SUBSTANCE: present invention relates to a method of producing 5-methyl-3-heptanone, which is a potential intermediate product in fine organic synthesis and a high-octane additive for motor fuel, as well as a polyfunctional catalyst. Disclosed method comprises conducting aldol-crotonic condensation of methyl ethyl ketone in a hydrogen atmosphere on a polyfunctional catalyst Pd/activated carbon, activated carbon is selected from activated carbon SKT-ZI and SKT-ZIK.

EFFECT: technical result is production of 5-methyl-3-heptanone with high selectivity.
