PEP Review X-1-4

Two Russian literature sources describe a process for producing styrene and aniline from nitrobenzene and ethylbenzene; nitrobenzene is reduced to aniline by hydrogen generated in the dehydrogenation of ethylbenzene. The exothermic heat of the nitrobenzene-to-aniline reaction more than compensates for the endothermic heat of the ethylbenzene to-styrene reaction. Under appropriate conditions and with the use of an appropriate catalyst the selectivities are very high for both reactions.
