Versuchsvorschrift

To a solution of 15.4 g (0.1 mole) of 2-mercaptobenzoic acid in 20 ml of ethanol was added a solution of 3.8 g (95 moles) of sodium hydroxide in 10 ml of ethanol. The ethanol was removed on a rotary evaporator at 50 mm and the residual solid was triturated several times with ethanol to remove any unreacted 2-mercaptobenzoic acid. The washed solid was dried under vacuum overnight to yield sodium 2-mercaptobenzoate: 10.8 g (61% yield).
