ABSTRACT:
An improvement in a process of forming an aldehyde or alcohol by the Oxo process wherein an olefinically unsaturated hydrocarbon is reacted with carbon monoxide and hydrogen in the presence of a group VIII B catalyst which improvement involves introducing the olefinically unsaturated hydrocarbon, hydrogen and carbon monoxide together with the catalyst into the bottom of a first reaction zone, allowing the reactants to rise in said reaction zone, passing liquid reactants from the top of said first reaction zone into the top of a second reaction zone, withdrawing liquid reaction mixture from the bottom of the second reaction zone and withdrawing gaseous reactants from the second reaction zone.
