CAUSTIC SODA (NaOH)

Caustic soda, also known as sodium hydroxide, is a substance utilized in various chemical processes across many industries. One such industry is the pulp and paper sector like PT. Pakerin, which employs this chemical for pulping and bleaching processes. The product NaOH is available in concentrations of 32% and 48%.
Here are 8 uses of caustic soda in daily life and industries:

1. NaOH is used to control acidity levels (pH) in water treatment facilities.
2. NaOH is employed in the regeneration process of producing demineralized water or purified water.
3. In the pulp and paper industry, NaOH is utilized for pulping and bleaching processes to separate ink from paper fibers before reuse.
4. In the textile industry, NaOH is used in cotton processing and in dyeing synthetic fibers like nylon and polyester.
5. In the soap and detergent industry, NaOH is used in saponification – hydration reaction where free hydroxide breaks the ester bonds between the fatty acids and glycerol of a triglyceride to produce soap.
6. NaOH also plays a vital role in the oil and gas industry. It is used to control alkalinity and pH, and to break down organic materials. Additionally, it aids in removing impurities like sulphur compounds and carbon dioxide.
7. NaOH is involved in the production process of epoxy resin.
8. In the realm of health, NaOH is utilized in the production of various medicines and pharmaceutical products, such as anticoagulants, cholesterol-reducing drugs, and pain relievers.
