Mixed butene streams containing butene-1 and isobutylene and optionally butene-2 are hydroformylated under conditions that hydroformylates all the monomers to yield a mixture of valeraldehydes. Higher temperatures and/or longer residence times and/or higher partial pressure of carbon monoxide than in conventional processes are used to ensure hydroformylation of all the monomers.

(EN) A process in which an alpha-olefin containing n carbon atoms is reacted with hydrogen and carbon monoxide in the presence of a complex rhodium-containing catalyst and a base to form aldehydes containing 2n+2 carbon atoms, wherein the reaction is conducted at a temperature and pressure sufficient to remove at least part of the product from the reaction mixture by vaporization or stripping. A process is also disclosed in which an alpha-olefin containing n carbon atoms is reacted with hydrogen and carbon monoxide in the presence of a complex rhodium-containing catalyst not containing halogen, free ligand and Lewis base to form aldehyde containing n+1 carbon atoms, wherein the reaction is conducted at a temperature and pressure sufficient to remove at least part of the product from the reaction mixture by vaporization. (FR) Procede, dans lequel une alpha-olefine contenant n atomes de carbone reagit avec de l"hydrogene et de l"oxyde de carbone en presence d"un catalyseur complexe contenant du rhodium et une base pour former des aldehydes contenant 2n+2 atomes de carbone, ou la reaction s"effectue a une temperature et a une pression suffisantes pour enlever au moins une partie du produit du melange de reaction par vaporisation ou stripping. On decrit egalement un procede dans lequel une alpha-olefine contenant n atomes de carbone reagit avec de l"hydrogene et de l"oxyde de carbone en presence d"un catalyseur complexe contenant du rhodium ne contenant pas d"halogene un liant libre et une base de Lewis pour former un aldehyde contenant n+1 atomes de carbone, la reaction ayant lieu a une temperature et a une pression suffisantes pour enlever au moins une partie du produit du melange de reaction par vaporisation.
