Abstract

In obtaining ammonium chloride and sodium bicarbonate by the reaction of ammonium bicarbonate with sodium chloride with the simultaneous precipitation of the two resulting salts, the reaction is carried out in the presence of substances which cause the ammonium chloride to separate in a coarsely crystalline form, and the resulting mixture of coarsely crystalline ammonium chloride and finely divided sodium bicarbonate is then subjected to a separating treatment. Suitable substances are urea, biuret and cyanuric acid. The separation is preferably effected by flotation, if desired with the addition of flotation agents such as oil or salts of fatty acids, the suspension of the finer crystals of sodium bicarbonate being decanted from the larger ammonium chloride crystals. Alternatively, other separating treatments such as sieving or screening may be employed.
