Participants

Reaction Steps

The sodium 3-chloro-2-hydroxypropanesulfonate reactant is added to the mixture, and the etherification reaction is conducted at 40° C over a period of 4 hours. The reaction mixture is neutralized to a pH of 8.3 with acetic acid, then filtered, washed twice with 50% isopropanol and once with 100% isopropanol.
