Abstract
The invention relates to a method of producing organic dinitramide salts, for instance, guanidine dinitramide and guanylurea dinitramide starting from ammonium dinitramide (ADN). A concentrated aqueous solution of ADN is reacted with a concentrated aqueous solution of an organic salt, whose anion is OH<-> or CO3<2-> which is capable of taking up a proton from the ammonium ion of ADN and transferring said ion to ammonia. The formed by-products, i.e. ammonia and possibly carbonic acid, are driven off from the solution, as well as a certain amount of water to maintain a concentrated solution. The organic dinitramide salt is then precipitated, for instance by cooling the solution. The method can be carried out as a continuous or semicontinuous process in a reactor (3), to which concentrated aqueous solutions of ADN (1) and organic salt (2), respectively, are supplied in equimolecular amounts. The solution is transferred from the reactor to a precipitation tank (7) where organic dinitramide salt (16) is precipitated and a supernatant is recirculated to the reactor.
