Synthesis process of benzophenone hydrazone is studied with benzophenone and 80%hydrazine as raw materials. Effects of material ratio, reaction time and concentration on aimed products are explored.
The structure of these adducts was proved through the reaction with 2, 4-dinitrophenylhydrazine in acidic medium, yielding the 2, 4-dinitrophenyl-hydrazone of the corresponding ketone.
