Another approach uses the coupling reaction of p-anisidine. In the presence of H202 and peroxidase (16), an oxidation product that contains two aromatic rings, benzoquinone-4-methoxyaniline, is formed stoichiometri-cally (92). Equations 14-16 indicate that an electron donor or hydrogen donor is required for peroxidase-mediated decomposition of H202. In two natural waters and one soil suspension, peroxidatic activity was identified by the stoichiometric removal of p-anisidine by the addition of H202 (in the dark) (16). This procedure provides an independent corroboration of the results obtained by Moffett and Zafiriou (1). However, this method does not quantify the relative importance of peroxidases versus catalases in the decomposition of H202.

There are surprisingly few alkoxyanilines for which thermochemical data seemingly exist. The simplest compounds are 2- and 4-methoxyaniline, known also as o- and p-anisidine. For the former compound, Reference 81 reports an enthalpy of formation of —46 kJmol-1 for the solid. For the latter, Reference 5 chronicles a value of —172 kJ mol-1, also for the solid. These two values are incomprehensively incompatible with each other. They are also incompatible with an enthalpy of formation derived from equation 2, ca —132 kJmol-1 (using—114.8 kJmol-1 for the enthalpy of formation of liquid anisole).

Reference 81 also reports the solid phase enthalpies of formation of the isomeric 4- and 5-nitro-2-methoxyanilines, —197 and —232 kJmol-1. These values are disconcertingly disparate. The two isomers should have very nearly identical enthalpies of formation because in both cases there are electron-donating groups para to the nitro group and so there should be comparable stabilization. From equation 18, an estimated value of solid anisole, and the average enthalpy of formation of m- and p-nitroaniline, a calculated enthalpy of formation of the nitro-o-anisidines is ca — 210 kJ mol-1.
