METHOD FOR PRODUCING 3-METHYLCYCLOALKENONE COMPOUND

Document Type and Number:

WIPO Patent Application WO/2020/067079

Kind Code:

A1

Abstract:

The present invention relates to a method for producing a 3-methylcycloalkenone compound and a method for producing muscone. A 3-methylcycloalkenone compound can be produced with high reaction efficiency by subjecting a diketone represented by general formula (1) (wherein n represents 8, 9, 10, 11 or 12) to an intermolecular condensation reaction in a gas phase in the presence of a zirconium oxide catalyst. Muscone can be produced with high efficiency by hydrogenating a 3-methylcyclopentadecenone compound produced by the method by a known method.
