NaS03C6H4(OH)+2H2O= 231.56. Synonym. - Sodium Paraphenolsulphonate.

Source

Phenolsulphuric Acid is formed by adding Sulphuric Acid to crystallized Carbolic Acid; on heating this mixture it becomes Paraphenol-sulphuric Acid, which yields a clear solution with water. C6H5OH+H2So4 =C6H5Hso4+H2O. Barium Carbonate is then added, and Barium Sulpho-carbolateis precipitated. 2C6H5Hso4+BaCo3=Ba(So3c6h4(OH) )2+H2O +Co2. This is treated with water and Sodium Carbonate; a solution of Sodium Sulphocarbolate is formed, and Barium Carbonate is precipitated. Ba(So3c6h4(OH) )2+Na2Co3=2NaSo3c6h4(OH)+BaCo3. The solution is evaporated to crystallization.

Characters

Colorless, transparent, rhombic prisms, odorless and having a cooling, saline, slightly bitter taste. Solubility. - In 4.8 parts of water; in 132 parts of Alcohol.

Dose, 5 to 30 gr.; .30 to 2.00 gm.

Action and Therapeutics of Sodium Sulphocarbolate

This substance is antiseptic, like carbolic acid, and may be used externally for this purpose. Internally it is occasionally given in the hope of controlling gastric fermentation.
