Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Sodium 1,2-Ethanedisulfonate | HCID 79220 | — |
| Solvent | Water | HCID 962 | — |
| Product | 1,2-Ethanedisulfonic Acid | HCID 8032 | 137.5% |
Reaction Steps
A solution of 3 g of 1,2-ethanedisulphonic acid disodium salt in 10 ml of water is introduced slowly into 200 ml of Dowex® 50 W×8 resin, and the product is eluted with 200 ml of demineralized water. The eluate is diluted by adding EtOH and concentrated under vacuum. 3.35 g of the expected product are obtained in the form of an oil which crystallizes at RT.
