| | Sodium p-toluenesulfinate Usage And Synthesis |
| Chemical Properties | White powder | | Uses | Sodium p-toluenesulfinate can be used as intermediate of pharmaceutical and dispersal dyes, and also can be used as curing agent of grouting material. | | Uses | p-Toluenesulfinic acid sodium salt is used as an intermediate for the preparation of pharmaceuticals and dispersal dyes. It acts as a curing agent of grouting material. It is also used as a discharge medium of dyes and pigments. Further, it serves as a chemical intermediate in the production of fluorescent pigments and fabric adhesive. In addition to this, it is used as an electroplating brightening agent and curing agent. | | Purification Methods | Recrystallise the salt from water (to constant UV spectrum) and dry it under vacuum, or extract it with hot *benzene, then dissolve it in EtOH/H2O and heat with decolorising charcoal. The solution is filtered and cooled to give crystals of the dihydrate.[Beilstein 11 I 718.] |
