Abstract: The present invention relates to a process for producing ammoniacal diammonium carbonate solutions, an aqueous phase being circulated by a jet nozzle as the reaction zone, and ammonia and carbon dioxide being introduced into the reaction zone at the same time, ammonia and carbon dioxide being drawn into the reaction zone, being absorbed in the aqueous phase in the process, and being reacted. The associated apparatus comprises a stock vessel (1) for the aqueous phase, a circulation pump (2) and a reactor (4) designed as a jet nozzle, which units (1, 2, 4) are connected to one another in a circuit via a suction line (5), a discharge line (6) and an offtake line, formed as a diffuser (11), of the reactor (4), the reactor (4) being equipped with three intake ports (13, 14, 15) for ammonia, carbon dioxide and exhaust gas from the stock vessel (1), and the stock vessel (1), for example, having inlets (12, 18) formed as plunge pipes for the circulated ammoniacal diammonium carbonate solution as well as for the aqueous phase feed, and a vent line (16) and an offtake line (19) for the ammoniacal diammonium carbonate solution being provided.
