Acetone azine, Me2C=N–N=CMe2, is the condensation product of two equivalents of acetone with one equivalent of hydrazine. It is an intermediate in the industrial production of hydrazine by the Atofina–PCUK cycle.[1]
On a laboratory scale, acetone azine is prepared by the direct reaction of acetone with hydrazine hydrate, with water being removed from the product by stirring with solid potassium hydroxide.[2][3]
