US Patent:

58178830, Oct 6, 1998

Filed:

Apr 15, 1997

Appl. No.:

8/843340

Inventors:

John Robert Briggs - Charleston WV
Kurt Damar Olson - Cross Lanes WV
Erik Bruce Tjaden - Charleston WV
Anil Sakharam Guram - Hurricane WV
Diane Lee Packett - South Charleston WV
Thomas Carl Eisenschmid - Cross Lanes WV
Elaine Susan Brigham - Charleston WV

Assignee:

Union Carbide Chemicals & Plastics Technology Corporation - Danbury CT

International Classification:

C07C 4550

US Classification:

568454

Abstract:

This invention relates in part to processes for producing one or more substituted or unsubstituted hydroxyaldehydes, e. g. , 6-hydroxyhexanals, which comprise subjecting one or more substituted or unsubstituted alkadienes, e. g. , butadiene, to hydrocarbonylation in the presence of a hydrocarbonylation catalyst, e. g. , a metal-organophosphorus ligand complex catalyst, and hydroformylation in the presence of a hydroformylation catalyst, e. g. , a metal-organophosphorus ligand complex catalyst, to produce one or more substituted or unsubstituted hydroxyaldehydes. The substituted and unsubstituted hydroxyaldehydes produced by the processes of this invention can undergo further reaction(s) to afford desired derivatives thereof, e. g. , epsilon caprolactone. This invention also relates in part to reaction mixtures containing one or more substituted or unsubstituted hydroxyaldehydes as principal product(s) of reaction.

Abstract:

This invention relates in part to processes for producing one or more substituted or unsubstituted hydroxyaldehydes, e. g. , 6-hydroxyhexanals, which comprise subjecting one or more substituted or unsubstituted alkadienes, e. g. , butadiene, to reductive hydroformylation in the presence of a reductive hydroformylation catalyst, e. g. , a metal-organophosphorus ligand complex catalyst, and hydroformylation in the presence of a hydroformylation catalyst, e. g. , a metal-organophosphorus ligand complex catalyst, to produce one or more substituted or unsubstituted hydroxyaldehydes. The substituted and unsubstituted hydroxyaldehydes produced by the processes of this invention can undergo further reaction(s) to afford desired derivatives thereof, e. g. , epsilon caprolactone.
