Rhodium catalyzed hydroformylation of internal olefins

Patent ·
OSTI ID:7203799

This patent describes a process for hydroformylation of an internal olefin selected from the group consisting of aliphatic olefins, cycloaliphatic olefins, and substituted derivatives thereof wherein the substituent comprises alkyl, aryl, alkaryl, aralkyl, cycloalkyl, hydroxy, -CHO and -C(O)OX, where X is alkyl of 1 to 20 carbon atoms in a hydroformylation reaction zone in the presence of a liquid rhodium triorgano phosphine catalyst system and in the presence of carbon monoxide and hydrogen to form the corresponding aldehydes. The improvement described here comprises employing in the the reaction zone at least one sterically hindered tricycloalkylphosphine.
