production method | 1. Method HSO 3 Cl + HNO 3 → NO 2 Cl + H 2 SO 4 add 63g of nitric acid (94.4%) to a three-neck flask equipped with a mechanical stirrer, a dropping funnel and an outlet pipe, the cooled flask was maintained below 5 °c, and 116.5G of chlorosulfonic acid was then added dropwise to the flask with stirring, and the resulting gas was directed to a cold trap trap through a washing flask containing concentrated sulfuric acid (96%). NO 2 Cl is condensed in a cold trap. 73-74g of NO 2 Cl can be obtained, corresponding to 90% of theoretical yield. |
