Process for the preparation of predominantly unbranched higher primary alcohols

摘要

To prepare higher, predominantly unbranched primary alcohols, olefins obtained in a Fischer-Tropsch synthesis are reacted with hydrogen and carbon monoxide in the presence of water and also rhodium in metallic form or in the form of a compound and in the presence of a water-soluble phosphine as catalyst. The reaction product obtained is hydrogenated. The water-soluble phosphines employed are compounds whose anion is a phosphine containing at least one sulphonated or carboxylated aromatic radical and whose cation is a quaternary ammonium or phosphonium ion.
