General Description

Deliquescent needles or large plates.

Purification Methods

Purify benzenesulfonic acid by dissolving it in a small volume of distilled H2O and stirring with slightly less than the theoretical amount of BaCO3. When effervescence is complete and the solution is still acidic, filter off the insoluble barium benzenesulfonate. The salt is collected and dried to constant weight in vacuo, then suspended in H2O and stirred with a little less than the equivalent (half mol.) of sulfuric acid. The insoluble BaSO4 (containing a little barium benzenesulfonate) is filtered off and the filtrate containing the free acid is evaporated in a high vacuum. The oily residue will eventually crystallise when completely anhydrous. A 32% commercial acid is allowed to fractionally crystallise at room temperature over P2O5 in a vacuum desiccator giving finally colourless deliquescent plates m 52.5o. The anhydrous crystalline acid is deliquescent and should be stored over anhydrous Na2SO4 in the dark and should be used in subdued sunlight as it darkens under sunlight. The main impurity is Fe which readily separates as the Fe salt in the early fractions [Taylor & Vincent J Chem Soc 3218 1952]. The S-benzylisothiuronium salt has m 148o (from EtOH/H2O). It is an IRRITANT to the skin and eyes. [See Adams & Marvel Org Synth Coll Vol I 84 1941, Michael & Adair Chem Ber 10 585 1877, Beilstein 11 IV 27.]
