PROCESS FOR PRODUCING OLEFINS

摘要

A process for converting an olefin having x carbon atoms into an olefin having x+1 carbon atoms wherein the process comprises the steps of: (i) reacting an olefin having x carbon atoms with carbon monoxide and hydrogen in the presence of a hydroformylation catalyst to produce an alcohol having x+1 carbon atoms, and (ii) dehydrating the alcohol produced in step (i) in the presence of a dehydration catalyst to produce an olefin having x+1 carbon atoms characterised in that the the hydroformylation catalyst used in step (i) is based on: (a) a source of cobalt, and (b) a ligand which contains phosphorus and nitrogen.
