実験手順
A process for the continuous manufacture of crystallized ammonium thiosulfate which comprises: reacting ammonia with oxygen containing sulfur dioxide in an ammonium thiosulfate solution to form ammonium bisulfite and ammonium sulfite at a pH of from 5.5 to 7.0 and a temperature of up to 80°C; and, in a second step, converting the ammonium bisulfite and ammonium sulfite in the solution formed with ammonia and sulfur to ammonium thiosulfate at a temperature of 105°C, said temperature being obtained by heating, if necessary.
