NOCl can be prepared by the direct combination of chlorine and nitric oxide. Alternatively, nitrosylsulfuric acid and HCl also affords the compound:
HCl + NOHSO4 → NOCl + H2SO4
It also arises from the combination of hydrochloric and nitric acids according to the following reaction:
HNO3 + 3 HCl → Cl2 + 2 H2O + NOCl
Although this mixture was used for dissolving gold for a long time the first description of the gas was done by Edmund Davy in 1831.
Reported in EPA TSCA Inventory.
