Sodium p-aminobenzoate Use and Manufacturing

Methods of Manufacturing

NaOH (1.2 g, 0.03 mol) was dissolved in 10 mL of distilled water and then 4.11 g (0.03 mol) p-aminobenzoic acid was added. After complete dissolution of the p-aminobenzoic acid, the water was evaporated and the yellow powder obtained was dried in oven at 80°C for 2 h. The resulting sodium salt (4.3 g, 90percent yield) was first analysed by IR spectroscopy.

Uses

Analgesic.

Manufacturing Info：

Benzoic acid, 4-amino-, sodium salt (1:1): ACTIVE
