white powder | [Uses]
Usually used as a supporting electrolyte for depositing polypyrrole membranes, ang also used as a solute to study the performance of resin particles. | [Flammability and Explosibility]
Nonflammable | [Synthesis]
A kind of neutralized wastewater for BHT production, in which sodium p-toluene sulfonate is contained in 19.8% and an alkali neutralizer (alkali containing sodium ions) is contained in 3.7%. The specific steps for the production of sodium p-toluene sulfon | [Purification Methods]
Dissolve it in distilled water, filter it to remove insoluble impurities and evaporate it to dryness. Then recrystallise it from MeOH or EtOH, and dry it at 110o. Its solubility in EtOH is not high (maximum 2.5%), so that Soxhlet extraction with EtOH may be preferable. Sodium p-toluenesulfonate has also been crystallised from Et2O and dried under a vacuum at 50o. [Beilstein 11 I 4, 11 II 6, cf Gibson & Reid J Chem Soc 879 1923.] |
