Abstract
The present invention relates to a process for the preparation of solid sodium hydrogen cyanamide by reacting cyanamide with sodium hydroxide in aqueous solution, the aqueous solution or suspension containing sodium hydrogen cyanamide being concentrated to dryness with the aid of a drier device which uses heating gases, preferably, a spray drier or atomization drier, and, if appropriate, the product then being dried. A pulverulent product with good flow properties, purity and storage stability is thereby obtained in an industrially simple manner.
