Process for preparing alcohols from carboxylic acids and process for preparing carboxylic acids.

摘要

An alcohol is produced in a high selectivity with a good yield from the corresponding carboxylic acid by reducing the latter with hydrogen in the presence of a rhenium catalyst in the coexistence of an organic base. An arylacetic acid, which is included in the starting carboxylic acid, can be produced in an excellent yield from the corresponding aryl aldehyde by reacting the latter with carbon monoxide and water in the presence of rhodium or its compound and hydrogen iodide.
