HYDROGENATION OF ALICYCLIC DIALDEHYDES TO ALICYCLIC DIOLS
摘要
A process for preparing one or more cyano-aliphatic aldehydes is described. The process comprises (a) preparing an olefinically-unsaturated cyano-aliphatic composition via a Diels Alder reaction of a diene and a dienophile composition; (b) contacting in a hydroformylation zone the olefinically-unsaturated cyano-aliphatic composition with carbon monoxide and hydrogen in the presence of a transition metal-organophosphorus ligand complex catalyst under hydroformylation conditions sufficient to prepare a hydroformylation product (c) mixing in an extraction zone the hydroformylation product composition with water under conditions sufficient to obtain by phase separation a nonpolar phase a polar phase comprising water and the one or more cyano-aliphatic aldehydes; (d) separating the one or more cyano-aliphatic aldehyde products from the hydroformylation product composition.
