Sodium p-toluenesulfonate Usage And Synthesis
Chemical Propertieswhite powder
UsesSodium p-toluenesulfonate was used as a supporting electrolyte for depositing polypyrrole membranes. It was also used as a solute to study the performance of resin particles.
UsesSodium?p-Toluenesulfonate can be used for high-efficiency for cleaning explosives.
UsesUsually used as a supporting electrolyte for depositing polypyrrole membranes, ang also used as a solute to study the performance of resin particles.
Flammability and ExplosibilityNonflammable
Purification MethodsDissolve 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.]
