Buy Caustic Soda online

Buy Caustic Soda online from USA based supplier.Caustic soda, also known as sodium hydroxide or industrial alkali, is an inorganic compound with the chemical formula NaOH. As a strong base, it is a white opaque plume crystal with a melting point of 328 degrees °C. Crisp, soluble in water and emits a lot of heat. Its aqueous solution is alkaline and feels creamy. Sodium hydroxide is easy to deliquescence in the air and can absorb carbon dioxide.

Sodium Hydroxide under MagnificationAs a basic chemical raw material, caustic soda and soda ash are two alkali in the “three acids and two alkali”. And it is often used as a raw material or reagent in industrial production and laboratories and has a wide range of uses. This product is commonly used in a variety of industrial and commercial applications, including chemical manufacturing, water treatment, food processing, textile manufacturing, cleaning agents and detergents,etc.

The form of caustic soda can be divided into liquid caustic soda (or liquid alkali) and solid caustic soda  (or solid alkali) according to its existing state. Liquid caustic soda is usually a colorless and transparent liquid, while solid caustic soda is colorless transparent crystal and comes in different forms such as flakes and granules.

Main Uses of Caustic Soda 99%

Caustic soda for sale can be widely used in chemical industry, metallurgical industry, petrochemical industry and daily life. For example, they can be used as detergent, saponification agent, peeling agent, acid neutralizer, complex masking agent, precipitating agent, precipitation masking agent, color developer, etc.

  • (1) As a raw material for manufacturing the detergents, soaps, textiles and paper.
  • (2) It can be used in water softening and treatment, oil field drilling mud, oil refining, hygiene and hygiene products.
(3) In the food industry, caustic soda 99% can be used as acid neutralizer, peeling agent, cleaning agent for empty bottles and cans, as well as decolorizing and deodorizing agents.

The Production Process of Sodium Hydroxide

Caustic soda is typically produced through the electrolysis of salt water (brine) using a process known as the chlor-alkali process. In this process, a direct electric current is passed through an aqueous solution of sodium chloride (NaCl), which results in the formation of chlorine gas (Cl2) at the anode and sodium hydroxide (NaOH) at the cathode. Hydrogen gas (H2) is also produced at the cathode.

The resulting sodium hydroxide solution is typically concentrated to increase its strength, and it can be further processed to produce solid caustic soda pearls or flakes. The byproduct chlorine gas is also an important industrial chemical and is used to produce a wide range of products, including PVC plastics and disinfectants.

Precautions with caustic soda

However, it should be noted that sodium hydroxide is highly corrosive to many substances, such as fibers, skin, glass, ceramics, etc. Once it comes into contact with skin or mucous membranes, it may cause burns. Therefore, when using caustic soda, we must wear protective equipment such as gloves, goggles, and protective clothing, and store it in a dry, ventilated, and cool place to avoid moisture and heat.
