Versuchsvorschrift

This compound was prepared by a double decomposition reaction between antimony trichloride and p-toluene sulfonic acid. A solution of 28.53 g (0.15 mole) of p-toluene sulfonic acid monohydrate in 150 cc of toluene was distilled until the water was removed. The anhydrous acid solution was then added dropwise to a solution of 11.4 g (0.05 moles) of antimony trichloride in about 50 cc of refluxing toluene. The solution became dark reddish brown, and the initially formed precipitate redissolved. Reflux continued for two hours, and the solution was then cooled. It contained 3.05 wt% antimony by calculation. Part of the solution was used to treat a catalyst for testing, as outlined below.
