METHOD FOR PRODUCING ALDEHYDE

摘要

PROBLEM TO BE SOLVED: To provide a method for producing aldehydes that brings an excellent alcohol conversion and aldehyde selectivity while suppressing generation of aldol condensates, etc.SOLUTION: The method for producing aldehydes includes a step of dehydrogenating primary alcohol in the presence of a catalyst composition. The catalyst composition is a first catalyst composition obtained by adding a potassium salt of a weak acid to a dehydrogenation catalyst containing copper as an active species.
