Sodium p-toluenesulfonate Usage And Synthesis
Chemical Properties
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.
Uses
Sodium?p-Toluenesulfonate can be used for high-efficiency for cleaning explosives.
Uses
Sodium 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.
Flammability and Explosibility
Non flammable
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.]
