Method for the preparation of alcohols and aldehydes by reacting olefins with carbon monoxide and hydrogen.

摘要

Olefins may be converted by reaction with carbon monoxide and hydrogen into good yields of aldehydes and alcohols in the presence of a ruthenium catalyst dispersed in a low-melting quaternary phosphonium or ammonium salt or base, the presence of which enables the conversion of C8-C20 internal olefins to be readily achieved, with high yields of alcohols in a manner not previously possible. The linearity of the alcohol and aldehyde products may be increased by dispersing the ruthenium catalyst in the low-melting quaternary phosphonium compound in association with a tertiary amine or phosphine.
