1-Bromo-3-chloropropane → 1-Propanesulfonic acid, 3-chloro-, sodium salt

Participants

Reaction Steps

1-Chloro-3-bromopropane (104.0 g) ethanol (250 ml), and water (90 ml) were stirred under reflux, and a solution of sodium sulphite (25.0 g) in distilled water (90 ml) was added to the stirred refluxing reaction mixture over a period of two hours. After the addition, refluxing was continued for a further 2 hours after which the excess alcohol and 1-chloro-3-bromopropane were removed by distillation. The remaining aqueous solution was evaporated to dryness on a steam bath and the product was recrystallised from alcohol to yield sodium 3-chloro-propane-sulphonate as a white crystalline solid.
