This invention relates to an improvement in a process for producing tert-butyl-derivatives of aromatic amines, e.g., para-phenylenediamine and toluenediamine by the reaction of isobutylene with the corresponding aromatic diamine in the presence of a highly acidic crystalline alumino-silicate catalyst. The improvement constitutes adding sufficient water to the catalyst to provide at least partial saturation of the catalyst during the reaction.
