Abstract
A process is provided, applicable to the production of hydrazine, which assures a continuous and constant production of azines without the need for detailed control of the working solution. According to the invention, azines are synthesized from oxygenated water, ammonia, and a reactant having a carbonyl group, by the following steps. The reactants are contacted with a working solution in order to obtain azine. The working solution is separated from the azine and possibly from the excess amount of reactant having a carbonyl group. All or part of the working solution is brought to a temperature above 130{degree}C, the water of reaction being eliminated before, after, or simultaneously. The working solution is then recycled to the first step. A product capable of maintaining azine production is introduced into the working solution at some point in the preceding stages. This product is preferably chosen from among acetic acid, ammonium acetate, and acetonitrile. The azines are hydrolyzed in order to obtain hydrazine hydrate. 1 fig.
