Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Sulfamic Acid | HCID 5987 | — |
| Reactant | Nitrobenzene | HCID 7416 | — |
| Reactant | Chlorosulfonic acid | HCID 24638 | — |
| Product | 3-Nitrobenzenesulfonyl chloride | HCID 8476 | 79% |
Reaction Steps
123.1 g (1.0 mol) of nitrobenzene and 582.5 g (5.0 mol) of chlorosulfonic acid are reacted as described in Example 20, but without addition of sulfamic acid. 175.1 g of dry 3-nitrobenzenesulfonyl chloride, corresponding to a yield of 79.0% of theory, are obtained.
