실험 절차

A solution of 4-hydroxybenzenesulfonic acid sodium salt dihydrate (20 g, 86 mmol) in 1 N aqueous sodium hydroxide (86 mL, 86 mmol) is stirred and heated at 50-60° C. for 1 h. The solution is concentrated in vacuo at 50° C. to give a solid. The solid is suspended in anhydrous toluene and concentrated in vacuo. This process is repeated twice. The solid is dried at 50° C. at high vacuum for 18 h to give 4-hydroxybenzenesulfonic acid disodium salt.
