Resumen Información suministrada por el agente en SIGEVA

The kinetics of the reaction of aniline with 2,4-dinitrochlorobenzene (2,4-DNCB) were studied in toluene in the presence of variable amounts of aniline. A linear dependence of the second-order rate coefficients, is observed, with a null intercept. Electron donor-acceptor (EDA) molecular complexes of 2,4-DNCB with benzene and with aniline, and also between aniline and the product, were clearly recognized and the stability constants of each one of these complexes were determined.
