PROCESS FOR THE PRODUCTION OF DIPHENYLAMINE

Diphenylamine is produced by contacting aniline with an alumina catalyst having at least about 30 percent by volume of its total porosity in the form of pores having a diameter of between about 120 and about 200 Angstroms and a sulfur content, as measured in the form of SO4, of less than about 0.02...
