The analysis of reaction and reaction products of 4:1, 2:1 and 1:1 stoichiometric reactions of aniline (AN) and formaldehyde (F) has been undertaken based purely on thermochemical considerations. Data on the enthalpy of formation and reaction are obtained from combustion and solution calorimetry. The same have been obtained by adopting Benson's theoretical thermochemical calculations. The computed and experimental $\Delta H^0_f$ and $\Delta H^0_r$ data are obtained for different possible reaction products of AN and F. Among them, compounds $NN^{\prime}$-diphenyl methylenediamine and anhydroformaldehyde aniline are identified as the reaction products of 4: 1, 2: 1 and 1 : 1 AN/F reactions. The structures of the products were further confirmed by spectral data. It was concluded that the thermochemical evaluation of structures yielded information about the nature of the products of AN and F reactions which agreed with experimental data and the results of other authors.
