Hs Code 28331100 Sodium Sulphate Anhydrous 99.2% As A Filler In Synthetic Detergents
Hs Code 28331100 Sodium Sulphate Anhydrous 99% As A Filler In Synthetic Detergents
Sodium sulfate is used in the production of sodium sulfide, pulp, glass, water glass, ceramic glazes, as well as a laxative and antidote for barium poisoning. It is a by-product of the production of hydrochloric acid from common salt and sulfuric acid. In the chemical industry, it is used for manufacturing sodium sulfide, sodium silicate, and other compounds. In the laboratory, it is used for washing away barium salts. In industry, it is used as a raw material for producing NaOH and H₂SO₄, as well as in papermaking, glassmaking, printing and dyeing, synthetic fibers, and leather production. In organic synthesis laboratories, sodium sulfate is commonly used as a post-treatment drying agent.
