NATRIUM HYDROXIDE / SODIUM HYDROXIDE / CAUSTIC SODA (NAOH)

18 August 2023

Natrium hydroxide, also known as caustic soda, sodium hydroxide, and lye, is a corrosive white crystalline solid and is generally used to neutralize acids, which are strong bases and the most common for various processes in various industries. Sodium hydroxide has the chemical formula NaOH which consists of sodium (Na), oxygen (O), and hydrogen (H) atoms. There are several forms of caustic soda that are widely available in the market:

  1. Caustic Soda Flake (NaOH content 98 - 99%)
  2. Caustic Soda Pearl / Prills (NaOH content 98 - 99%)
  3. Caustic Soda Pellet (NaOH content 98 - 99%)
  4. Caustic Soda Liquid (NaOH content 48 - 50%)

 

Here are several general properties of Sodium Hydroxide:

  1. Strong base
    • Sodium hydroxide is a strong base because it has a high affinity for hydrogen ions (H+) and donates hydroxide ions (OH-) in water. With the reaction equation, as follows:
    • NaOH + H2O --> Na+ + OH- + H2O
  2. Corrosive
    • Sodium hydroxide is corrosive and can cause irritation or injury to the skin, eyes, and other tissues. Therefore, it is highly recommended to use adequate and complete personal protective equipment (PPE).
  3. Crystal
    • NaOH is a white crystalline solid which has a high solubility in water.

 

Sodium Hydroxide applications in various types of industries :

  1. Soap Industry
    • Sodium hydroxide is an important raw material in the production of various chemical compounds, one of which is soap, detergent, and other cleaning products industry. Sodium hydroxide is used in the saponification process (turning vegetable oil into soap).
  2. Petrochemical Industry
    • Sodium hydroxide is used in the process of refining petroleum and natural gas processing. Sodium hydroxide also plays a role in removing odors from hydrogen sulfide (H2S) and mercaptans.
  3. Pulp & Paper Industry
    • Sodium hydroxide is used in the process of bleaching pulp and paper making with the aim of removing lignin from wood fibers, process of de-inking scrap paper, and whitening pulp.
  4. Water Treatment Industry
    • Sodium hydroxide is used in water treatment as a chemical to neutralize the pH of water and precipitate heavy metals.
  5. Pharmaceutical Industry
    • Sodium hydroxide is used in the production of some drugs and other pharmaceutical products (not as an active ingredient).
  6. Smelting Industry
    • For example aluminum smelters, sodium hydroxide is used in the process of smelting and refining aluminum from bauxite ore.
  7. Textile Industry
    • Sodium hydroxide is used for the dyeing process of synthetic fibers (example, rayon, nylon, polyester, polypropylene, etc.).
