  • Publication number: 20110201832
    Abstract: A process is provided for the synthesis of furan and related compounds by vapor phase decarbonylation of furfural and derivatives, using a palladium/alumina catalyst that has been promoted with an alkali carbonate. Catalyst lifetime is improved. The catalyst can be regenerated in situ by feeding a mixture of air and steam, with a composition of between about 2% and about 40% air, to the catalyst bed at a temperature between about 300° C. and about 500° C.

  • Publication number: 20110196126
    Abstract: A process is provided for the synthesis of furan and related compounds by vapor phase decarbonylation of furfural and derivatives. The reaction rate, conversion, and selectivity are enhanced by adding water to the feed. The process can be run at lower temperatures than in similar processes run with essentially dry furan and related compounds.

  • Publication number: 20100160693
    Abstract: A process is provided for making a reaction product comprising 1-butanol by contacting a reactant comprising ethanol containing a significant amount of water with a decomposed hydrotalcite catalyst. The catalyst may be 1) hydrotalcites which have been thermally decomposed, either partially or fully, to form catalytically active species; 2) combinations of hydrotalcites (optionally containing transition metals) and metal carbonates; and 3) hydrotalcites (optionally containing transition metals) surface-impregnated with a transition metal nitrate, where catalysts 2) and 3) have also been thermally decomposed, either partially or fully, to form catalytically active species. The catalyst, at a selected reaction time, has greater activity when the ethanol contains water as compared to when the ethanol is anhydrous.

  • Patent number: 5536873
    Abstract: 3-pentenoic acid or the R ester of pentenoic acid is produced by treating pentenoyl chloride in a reactive distillation zone with ROH where R is hydrogen or hydrocarbon of 1 to 6 carbon atoms. Butadiene may be reacted with HCl that is formed by the hydrolysis of pentenoyl chloride, and the butadiene converted to chlorobutene, and the chlorobutene reacted with carbon monoxide to form pentenoyl chloride.
