Unlike studies suggesting beta-keto acid as an undetectable intermediate.of ketonization, hexanoic anhydride ((CH3(CH2)(4))COOCO(CH2)(4)CH3) was observed to form as a result of the condensation of two hexanoic acid molecules by the loss of a water molecule. In order to investigate the role of hexanoic anhydride on the ketonization reaction, this kinetic study compared the performances of the reaction rate equations under different models for the reaction mechanism. Results indicate that ketonization occurs by the condensation of two hexanoic acid molecules producing hexanoic anhydride, followed by decarboxylation to produce 6-undecanone. By contrast, the formation of a beta-keto acid is not observed in any experimental attempt.
