Abstract

Alcohols are catalytically oxidized to aldehydes, in particular to benzaldehyde and diformylfuran, which are useful as intermediates for a multiplicity of purposes. The invention also relates to the polymerization of the dialdehyde and to the decarbonylation of the dialdehyde to furan.

Claims (4)

1. A process for the preparation of furan comprising converting 2,5-diformylfuran into a furan and furfural product mix via decarbonylation in the presence of a catalytic amount of a compound consisting essentially of an optionally supported metal selected from Periodic Group VIII.

2. The process of claim 1 wherein the process further comprises converting the furan and furfural product mix via decarbonylation into furan in the presence of a catalytic amount of a compound consisting of an optionally supported metal selected from Periodic Group VIII.

3. The process of claim 1 wherein the catalyst is supported on a catalyst support member.

4. The process according to claim 3 wherein the metal is palladium and the catalyst support member is carbon.
