Outline of Final Research Achievements

Typical Cativa carbonylation catalyst was found to work to the reverse decarbonylation reaction. For example, decarbonylation reaction of stearic acid was effectively catalyzed by H2IrCl6/Ru(CO)4I2 to form carbon monoxide, water, and heptadecenes. The same reaction system also catalyzed water gas shift reaction of thus generated carbon monoxide and water leading to hydrogen and carbon dioxide. Catalytic decomposition of butanoic acid by Vaska complex proceeded to give propyrene and CO. Ethylene was formed by decarboxylation of acrylic acid in the presence of Vaska complex as a catalyst. On site reaction systems, where in-situ generated reactive small molecules were immediately consumed, were tested in several cases.
