Chemical properties

White loose crystal, solubility in water is 185.6 under standard conditions; melting point is 131°C, boiling point is 160°C (decomposition), can absorb moisture in the air; insoluble in methanol and ethanol. Hygroscopic. Thermal decomposition, release a lot of inert gas.

Use

●  Used as analytical reagent, herbicide and fabric water repellent

●  Widely used in pesticides, printing and dyeing, tobacco, building materials, textiles and other industries

Production method

●  Under pressure, the purified sulfamic acid is dissolved in liquid ammonia, then decompressed, and the excess liquid ammonia is evaporated to obtain;
●  It is obtained by reacting sulfur trioxide and liquid ammonia as raw materials under pressure;
●  It is obtained by metathesis reaction with sulfamic acid with ammonium bicarbonate as raw material.
