Abstract
Hydroxybenzenes are converted to the corresponding amines by contacting the hydroxybenzene and ammonia at temperatures of about 250.degree.-550.degree. C. and pressures of about 0-5000 psig with a novel siliceous composition prepared by impregnating porous silica with aluminum hydride and subsequently heating the impregnated silica to a temperature of from about 300.degree. C. to about 900.degree. C. in a non-oxidizing environment.
Claims15
A process for conversion of arylhydroxides to the corresponding amines which comprises contacting the arylhydroxide and ammonia at about 250.degree. C. to about 550.degree. C. with a catalyst prepared by a process which comprises impregnating a substantially dehydrated amorphorous silica gel with aluminum hydride dissolved in an anhydrous, non-hydroxyl containing organic solvent, drying the impregnated silica to remove the solvent and subsequently heating the impregnated silica at a temperature of about 300.degree. to about 900.degree. C. in a non-oxidizing atmosphere.
