摘要
1. A process for the continuous production of aqueous ammonium thiocyanate solutions by reaction of ammonia and carbon disulfide and decomposition of intermediate products formed at temperatures of 90 to 150 degrees C in the presence of water or aqueous ammonium thiocyanate solutions using active carbon as catalyst, characterized in that the reaction of ammonia and carbon disulfide and the decomposition of intermediate products formed are carried out under a pressure in the range from 2 to 7 bar.
