HYDROFORMYLATION PROCESS WITH IMPROVED ISO-SELECTIVITY

摘要

Disclosed is a process for hydroformylation of a-olefin wherein said a-olefm is reacted with carbon monoxide or carbon monoxide and hydrogen and/or a reducing agent in presence of a catalyst complex based on a rhodium precursor and a ligand mixture comprising at least 1% by weight of triphenylphosphine and at least 5% by weight of diphenylcyclohexylphosphine, tris-(o-tolyl)phosphine, tris-(p-tolyl)phosphine or (2-methyl- phenyl)diphenylphosphine.
