Abstract
The rearrangement of phenylhydrazine to o- and p-phenylenediamines was carried out over ZSM-5 and its modified catalysts. Sm and V showed the promoting effect. In presence of ammonia flow Ga and Cr modified ZSM-5 catalysts gave good yields of o- and p-phenylenediamines. The better temperature and WHSV for this reaction are found to be 400°C and 0.25 h-1 respectively. The SiO2/Al2O3 catalyst showed very low ortho-para selectivity when compared with zeolite catalysts.
