Sodium chlorosulfonate is an inorganic chemical compound with the formula NaSO3Cl. It is the sodium salt of chlorosulfuric acid.
Contents
Properties
Chemical
Sodium chlorosulfonate reacts strongly with water, producing sodium bisulfate and HCl fumes.[1]
- NaSO3Cl + H2O → NaHSO4 + HCl
Sodium chlorosulfonate decomposes when heated to form sodium sulfate, chlorine and sulfur dioxide.[2]
- 2 NaSO3Cl → Na2SO4 + Cl2 + SO2
Sodium chlorosulfonate reacts with ammonia at -33 °C to form ammonium sulfamate, at around 53% yield. The reaction is describe as vigorous. Ammonium sulfate and ammonium imidodisulfonate are produced as side products.[3]
- NaSO3Cl + 2 NH3 → NH4SO3NH2 + NaCl
Addition of conc. sulfuric acid will produce chlorosulfuric acid, which can be distilled off.[4]
Physical
Sodium chlorosulfonate is a colorless solid, that readily and violently reacts with water, and some organic solvents, like alcohols, esters and ammonia or amines. In a perfectly dry environment, the compound should be odorless, but any trace of moisture may induce hydrolysis, giving it an acidic smell.
Availability
There doesn't appear to be anyone selling this stuff.
Preparation
Chlorosulfuric acid will react with dry sodium chloride to yield sodium chlorosulfonate.[5]
- HSO3Cl + NaCl → NaSO3Cl + HCl
Alternatively, it can be produced by the reaction of sulfur trioxide with sodium chloride. Anhydrous hydrogen chloride can be used as reaction solvent[6]
- SO3 + NaCl → NaSO3Cl
Projects
- Compound collecting
- Make ammonium sulfamate
- Make chlorosulfuric acid
Handling
Safety
Sodium chlorosulfonate reacts with water and moisture, releasing HCl fumes, which are highly corrosive. Thus, one must wear proper protection when handling this compound.
Storage
Should be kept in airtight containers, free of any moisture. Schlenk flasks are a possibility for long-term storage.
Disposal
Should be added very carefully to crushed ice, in a closed box.
