CATALYTIC SYNTHESIS OF ALDEHYDES BY DIRECT HYDROGENATION OF CARBOXYLIC ACIDS |
摘要 |
A process which makes it possible to prepare aldehydes under mild reaction conditions with a high efficiency through the reduction of carboxylic acids with molecular hydrogen. Specifically, a process of reducing an organic carboxylic acid with molecular hydrogen in the presence of a catalyst into an aldehyde corresponding to the acid, characterized by conducting the reduction in the presence of a dehydrating agent such as a carboxylic anhydride.
