Benzene Sulfonic Acid (C6H5SO3H, CAS 98-11-3) is a strong organic acid, commonly handled as a viscous solution with a specific gravity of about 1.3. It is corrosive to skin and metals. It is used as an acid catalyst for resins and esterification, and as an intermediate for phenol, resorcinol, detergents and pharmaceuticals. Tanks for benzene sulfonic acid must resist strong acid. Use the compatibility ratings to choose the right tank resin, fittings and gaskets.
HDPE is the recommended tank material for Benzene Sulfonic Acid, rated Excellent. Avoid polypropylene and nylon tanks; CPVC and polypropylene fittings; Buna-N and EPDM gaskets; aluminum hardware.
