Abstract
PURPOSE: To raise the yield of nitrous oxide in the manufacture of the oxide from sulfamic acid and nitric acid by adding sulfuric acid to the nitric acid or circulating reaction waste liquor contg. sulfuric acid to keep the total concn. of nitric acid and sulfuric acid in a fluid for reaction at a high value.
CONSTITUTION: When nitrous oxide is manufactured by the reaction of the equation in reactor 1 having a cooling surface such as a jacket or a coil, starting material sulfamic acid 2 is previously mixed with circulating fluid 4 contg. sulfuric acid by means of premixer 3 to prepare slurry 5, and slurry 5 and nitric acid 6 are fed separately and simultaneously to reactor 1 in which a fluid for reaction is retained. The amount of nitric acid used is restricted to such a degree that it exceeds the amount of sulfamic acid by equivalent. When sulfuric acid in the circulating fluid is insufficient, sulfuric acid is added to premixer 3 or reactor 1 to keep the total concn. of nitric acid and sulfuric acid in the fluid for reaction at ≥50%, and the reaction temp. is adjusted to 80W110°C.
