Azines, e.g., ketazines, are continuously produced by (i) establishing a loop having an azine reaction medium circulating therein, such loop including an azine reaction zone, means for separating azine final product from the circulating reaction medium, means for heating the reaction medium and for purging water therefrom, and means for recycling heated and purged reaction medium to the azine reaction zone, (ii) introducing hydrogen peroxide, ammonia and a carbonyl compound into the circulating reaction medium in the azine reaction zone, (iii) withdrawing azine final product thus formed from the circulating reaction medium. downstream of the azine reaction zone, (iii) thereafter purging water from the circulating reaction medium to maintain the volume thereof essentially constant, (iv) heating the circulating reaction medium to a temperature of at least 130° C., (v) recycling thus heated reaction medium to the azine reaction zone, and (vi), at any point along the loop, introducing a reagent into the circulating reaction medium as to essentially maintain the equilibrium of the azine-forming reaction; the final product azines are conveniently hydrolyzed into hydrazine hydrate. |

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. |

PURPOSE: To continuously and stably produce azine by reacting hydrogen peroxide, ammonia and a compd. having a carbonyl group while bringing them into contact with a circulating operation liquid and subsequently successively separating azine and reaction water from the circulating operation liquid.
CONSTITUTION: In a reaction apparatus 20, hydrogen peroxide 3, ammonia 4 and a compd. having a carbonyl group (e.g.; acetone, methyl ethyl ketone) 1 are brought into contact with an operation liquid 5 to be reacted at 30-70°C. Azine and an excessive amt. of the compd. having the carbonyl group are separated from the operation liquid and azine is hydrolyzed 60 to obtain hydrolyzed hydrazine 8 and the reaction product and an excessive amt. of the compd. having the carbonyl group recovered after hydrolysis are circulated 1 to the reaction apparatus 20. The operation liquid 9 is sent to a tower 40 and reaction water and a small amt. of ammonia are removed 10 and a tower bottom component is sent to an ion exchange resin absorbing apparatus 50 to remove heavy impurities to be circulated to the reaction apparatus 20. The operation liquid is prepared by forming org. or inorg. oxygen acid, its ammonium salt or its deriv. into a soln.
