Sodium Hydroxide → Ethanesulfonic acid, 2,2'-dithiobis-, disodium salt

Participants

Reaction Steps

The ongoing S-acetyl-2-mercaptoethane sulfonic acid, sodium salt (20 g) is dissolved in water and added 1N sodium hydroxide to adjust the pH to 9.0. The reaction mixture is the then stirred while bubbling oxygen for 48 hours. The aqueous portion is then concentrated and crystallized out the product directly. Yield is found to be 80%. The product is characterized by NMR and corroborated the structure with the authentic sample.
