Mechanism Of The Reaction

Benzofurazan oxides are formed in excellent yield when certain substituted-2-nitroanilines react with iodosobenzene diacetate in benzene containing 1 per cent. (by volume) of acetic acid. The kinetics of this reaction have been studied. It is considered that the mechanism of the reaction involves a reversible reaction of the 2-nitroaniline with iodosobenzene diacetate to form acetic acid and an intermediate which is then converted to benzofurazan oxide, iodobenzene, and acetic acid. This reaction is therefore similar to the reaction of iodosobenzene diacetate with glycols. The rates of oxidation of substituted-2-nitroanilines could not be correlated with the electrical effect of the substituent. The reasons for this are discussed in detail.

Apparent Activation Energies

The rate of Co(III) reduction under inert atmosphere in the presence of p-toluic acid (PTA) and hydrobromide obeys the rate law d[Co(III)]/dt = k[Co(III)]2 [Co(II)]-1 [PTA] [HBr]. The proposed reaction mechanism involves the reduction of Co(III) by Br- ions and formation of a cation-radical from p-toluic acid. p-Xylene is attacked by bromine species and not directly by Co(III). The rate constants of Co(III) and Br- consumption as well as apparent activation energies were estimated.

Reaction kinetics for the oxidation of propane over diluted-leached MoVTeNb is described. This paper is focused on the study of determination of the orders of carbon dioxide, acetic acid and acrylic acid formation. Deep oxidation of propane to carbon dioxide is first order with respect to hydrocarbon, and partial order (0.31) with respect to oxygen. The selective oxidation of propane to acrylic acid is partial order (0.49) with respect to hydrocarbon and partial order (0.09) with respect to oxygen.
