Caustic soda, commonly known as Sodium hydroxide, caustic soda and caustic soda, is a kind of strong caustic soda with strong corrosiveness. caustic soda contents include 50% liquid 99% thin slice 99% pearl. It is generally in sheet or block form. It is easy to dissolve in water and form alkaline solution. And caustic soda is also deliquescent and easy to absorb water vapor and carbon dioxide from air. Hydrochloric acid can be added to check whether it has deteriorated.


Research History of caustic soda:

Caustic soda has long been known as an alkaline substance. In 1787, Doctor Nicolas Leblanc invented a suitable process for preparing caustic soda from salt and carried out large-scale production. In 1887, Swedish chemist Arenius founded the theory of acid-base ionization (that is, the theory of acid-base in aqueous solution). He proposed that all cations produced by ionization in aqueous solution are substances of hydrogen ion, and alkali is substances of hydrogen-oxygen ion in aqueous solution. Since then, the alkalinity of caustic soda has been clearly defined.


Physicochemical Properties of caustic soda:

Physical and chemical properties of caustic soda include physical and chemical properties. The physical property of caustic soda is that it is a white translucent crystalline solid. Its aqueous solution is astringent and slippery. Caustic soda is easily deliquescent in air and is often used as a desiccant. Not only that, but caustic soda is also very soluble in water, releasing a lot of heat when dissolved. Caustic soda is also soluble in ethanol, glycerol and so on. The chemical property of caustic soda is that it can react with any protonic acid in acid-base neutralization. Similarly, caustic soda solution can react with salt solution in double decomposition and coordination.


Use of caustic soda:

In national economy, and widely used in detergent, petroleum drilling, oil-refining, papermaking, glassmaking, textile, printing dyeing, metallurgy, synthetic fiber, pesticide, petrochemical, pharmacy, food, and power industries. Caustic soda is widely used in the national economy, and many industrial sectors need sodium hydroxide. Caustic soda is the most used sector in the manufacture of chemicals, followed by paper, aluminium, tungsten, rayon, rayon and soap manufacturing. In addition, in the production of dyes, plastics, pharmaceuticals and organic intermediates, the regeneration of old rubber, the electrolysis of metal sodium, water and inorganic salts, the preparation of borax, chromium salts, manganate, phosphate, etc., also need to use a large number of caustic sodas. At the same time, caustic soda is one of the important raw materials for the production of polycarbonate, super absorbent polymer, zeolite, epoxy resin, sodium phosphate, sodium sulfite and a large number of sodium salts.
