Abstract
Benzophenone-hydrazone is prepd from benzene and carbon-tetra: chloride and/or phosphene at 5-15 deg C in the presence of aluminium-tri; chloride, a Friedel-Crafts catalyst. Resulting chloro-di:phenylmethane is hydrolysed by 20-40 mols water at the mixts. b.pt; pH is set to 2-2.5 and 1-1.2 mols hydrazine-hydrate are added.
