What is Caustic Soda?
Caustic soda – or sodium hydroxide – is natural co-product of chlorine production. Furthermore indeed, laws of chemistry define that for every tonne of chlorine you produce, about 1100 kg of caustic soda is also produced, together with 28 kg of hydrogen.
In addition, it`s basic reactant in making wide range of organic chemicals. 32 % of caustic production uses in this way.
Paper, pulp and cellulose industries are major users of caustic soda. Furthermore, inorganic chemicals like paints, glass and ceramics also uses in fuel cell production and cosmetics are also very important.
In addition NaOh is uses on: food industry, water treatment (flocculation of heavy metals and acidity control), soaps and detergents sectors, textile sector (bleaching agent), mineral oils (preparation of greases and fuel additives) and the synthesis of synthetic fiber rayon. 4% used in refining aluminium from its ore bauxite.
Furthermore it has miscellaneous applications, like the synthesis of pharmaceutical compounds, rubber recycling and the neutralization of acids.
