Caustic Soda

We are specialized in providing the Caustic Soda. Sodium hydroxide (NaOH), also known as lye and caustic soda, is a caustic metallic base. It is used in many industries, mostly as a strong chemical base in the manufacture of pulp and paper, textiles, drinking water, soaps and detergents and as a drain cleaner.
Pure sodium hydroxide is a white solid available in pellets, flakes, granules, and as a 50% saturated solution. It is hygroscopic and readily absorbs water from the air, so it should be stored in an airtight container. It is very soluble in water with liberation of heat. It also dissolves in ethanol and methanol, though it exhibits lower solubility in these solvents than does potassium hydroxide. Molten sodium hydroxide is also a strong base, but the high temperature required limits applications. It is insoluble in ether and other non-polar solvents. A sodium hydroxide solution will leave a yellow stain on fabric and paper.
Applications :
Pulp and Paper Industry
The pulp and paper industry is the largest consumer of caustic soda worldwide. Uses include the de-inking of waste paper and water treatment, as well as being a raw material in the pulping and bleaching processes.Textile Industry
Caustic soda is used in the chemical processing of cotton, including desizing, scouring, mercerization, and dying synthetic fibers, such as nylon and polyester.
Soaps and Detergents Industry
Caustic soda is the alkali material frequently used in the saponification or conversion of fat, tallow and vegetable oils in the soap manufacturing process. The largest use of caustic soda in detergents is in the manufacture of anionic surfactants.Bleach Manufacturing Industry
Caustic soda is used to make bleach (sodium or calcium hypochlorite)Petroleum Products Industry
Caustic soda is used in the exploration, production and processing of petroleum and natural gas. A major use of caustic soda is in the removal of objectionable acidic materials, such as H2S and mercaptans, from hydrocarbons and off-gases generated in processing.Aluminum Industry
The production of alumina from bauxite is a major end-use application for caustic soda. It is used to dissolve bauxite as a first step in the production of aluminum.
Chemical Processing Industry (CPI)
Caustic soda is a basic feedstock for a wide range of downstream products in the chemical processing industry. It is used as an intermediate and as a reactant in processes that produce solvents, plastics, synthetic fabrics, adhesives, coatings, herbicides, dyes, inks, pharmaceuticals, and many more industrial products. It is also used for the neutralization of acidic waste streams and scrubbing of acidic components from off-gases.
