Title:
PROCESS FOR SELECTIVELY HYDROFORMYLATING DIOLEFIN
Document Type and Number:
WIPO Patent Application WO/1988/007033
Kind Code:
A1
Abstract:
A process for selectively hydroformylating a diolefin, which comprises reacting a (1-arylethenyl)-vinylbenzene with carbon monoxide and hydrogen under the conditions of 40 to 200°C in reaction temperature and 5 kg/cm2 or above in reaction pressure in the presence of a transition metal carbonylation catalyst to thereby selectively hydroformylating only the vinyl group and produce alpha-((1-arylethenyl)phenyl)-propionaldehyde. The starting material to be hydroformylated may be a mixture of the vinylbenzene with a 1,1-di(substituted aryl)ethylene not substituted by a vinyl group.
