Caustic Soda Flakes NaoH

Sodium hydroxide (NaOH) is an inorganic compound composed of sodium cations and hydroxide anions, with a molecular weight of 39 and a melting point of 323°C. This strong alkaline substance, commonly known in the industry as caustic soda or lye, appears as a white solid. Sodium hydroxide is available in both liquid and solid (flake) forms.

Liquid sodium hydroxide typically has a concentration of 30–50% and is widely used in water treatment for pH regulation and in the food industry. Solid sodium hydroxide, or caustic soda flakes, is produced by evaporating liquid sodium hydroxide and has a purity level of 99%. This article by Raeis Trading introduces caustic soda flakes (NaOH) and explores their industrial applications.

Production of Caustic Soda Flakes (NaOH)

Caustic soda flakes are primarily produced using two methods: the electrolysis of sodium chloride solutions and the older soda-lime process. The modern electrolysis method involves the following steps:

1. Mercury Cell Process: A mercury flow acts as a cathode, where sodium amalgam is formed and then reacts with water to produce sodium hydroxide.
2. Electrolysis Process: Electrolytes move from the anode to the cathode, and through a diaphragm separation process, sodium hydroxide, chlorine gas, and hydrogen gas are generated.

Caustic soda flakes are highly hygroscopic, meaning they readily absorb moisture from the air. When dissolved in water, the solution releases significant heat, making it highly reactive and corrosive.

Given their unique properties, caustic soda flakes are widely utilized across various industries, as discussed below.

Applications of Caustic Soda Flakes (NaOH)

Thanks to their distinctive characteristics, caustic soda flakes have extensive industrial applications and serve as a critical raw material for many products. Below are some of their key uses:

1. Oil and Gas Industry

Used in refining processes and for neutralizing acidic substances.

2. Paper and Pulp Industry

Essential for digesting wood pulp and recycling paper.

3. Water Treatment

Used to adjust the pH and remove impurities in water purification processes.

4. Soap and Detergent Manufacturing
