ABSTRACT:
A process for reducing chloronitrobenzenes to the corresponding chloroanilines using a combination ruthenium-platinum catalyst is disclosed. The ratio of ruthenium to platinum in the catalyst is from 75:1 to 30:1. The pressure used is from 200 to 800 psi with from 400 to 600 psi being the preferred range. The temperature used is from 70.degree. to 160.degree. C. with from 110.degree. to 150.degree. C. being the preferred range.
