Process for the preparation of azines.

摘要

Process for the synthesis of azines from aqueous hydrogen peroxide, ammonia and a reactant bearing a carbonyl group, characterised in that this reactant is brought into contact with an amide of a weak acid and the ammonium salt corresponding to this acid and in that the azine obtained is then isolated.
The invention also relates to processes in which the reaction takes place in the presence of any mixture containing an amide and the azine is then recovered and the remainder of the reaction mixture is treated to regenerate the amide.
