Abstract
The invention concerns processes for oxidizing an alcohol to produce a carbonyl compound. The processes comprise contacting the alcohol with (i) a gaseous mixture comprising oxygen; and (ii) an amine compound in the presence of a catalyst, having the formula: where each of R1-R12 are independently H, alkyl, aryl, CF3, halogen, OR13, SO3R14, C(O)R15, CONR16R17 or CO2R18; each of R13-R18 is independently alkyl or aryl; and Z is alkl or aryl.
Claims17
A process for oxidizing an alcohol to produce a carbonyl compound, said process comprising contacting the alcohol with
- (i) a gaseous mixture comprising oxygen;
- and
- (ii) an amine compound;
- said contacting occurring in the presence of a catalyst, said catalyst comprising two nitrogen-containing heterocycles complexed with vanadium and having the formula:
- wherein:
- each of R1-R12 are independently H, alkyl, aryl, CF3, halogen, OR13, SO3R14, C(O)R15, CONR16R17 or CO2R18;
- each of R13-R18 is independently alkyl or aryl;
- and
- Z is alkl or aryl.
