Benzenesulfonic acid sodium salt Usage And Synthesis

Chemical Properties

off-white crystalline powder

Uses

Sodium benzenesulfonate has been used in Raman spectroscopic determination of molecular structural features in sulfonated polystyrene resins. It was used as electrolyte in formation of polypyrrole coatings with varying surface morphology on stainless steel. It was used in the synthesis of 1-butyl-3-propanenitrile imidazolium benzenesulfonate.

Purification Methods

Crystallise it from EtOH or aqueous 70-100% MeOH, and dry it under a vacuum at 80-100o. [Beilstein 11 H 28, 11 I 10, 11 II 18, 11 III 33, 11 IV 27.]
