Abstract
Azines, well suited for hydrolysis into hydrazine, are prepared in high yields by reacting ammonia, aqueous hydrogen peroxide and a carbonyl compound reactant in the presence of a catalytically effective amount of a catalyst medium therefor, i.e., an aqueous solution of ammonium acetate and acetamide or of acetamide and acetic acid, but in the absence of CO.sub.2.
