Hydrogen formation during hydrazine reduction of oleic acid

Hydrogen has been detected in the gas phase when oleic acid is reduced with hydrazine. The rate of hydrogen production has been followed during this reaction by coupling a gas chromatograph to an automated manometric system. The observation of hydrogen evolution alters prior concepts which assume that nitrogen is the only gas given off. Equations involving hydrazine autoxidation, hydrogen production, and reduction of double bonds have been postulated and their stoichiometry studied.
