Industrial Grade Caustic Soda Sodium Hydroxide The Essential Chemical for Industries
Product introduction
Sodium hydroxide, with the chemical formula NaOH, is commonly known as caustic soda, lye or caustic soda. It is a white semi-transparent crystalline solid with strong corrosiveness. It is highly soluble in water and releases a large amount of heat. Its aqueous solution is strongly alkaline and has a slippery feeling. It is widely used in the industrial field. As a basic chemical raw material, it can be used in industries such as soap manufacturing, papermaking, textile and dyeing. In soap production, it converts oils into soap and glycerol through saponification reaction. It is used to decompose lignin in the papermaking process to prepare pulp. It can remove grease and impurities from fabrics in the textile industry. In chemical production, sodium hydroxide is an important raw material for preparing various compounds. For instance, sodium hypochlorite can be produced by reacting with chlorine gas, and it can also be used to neutralize acidic substances and adjust the pH value of solutions. In the field of medicine, its dilute solution can be used for disinfection and wound cleaning. In the food industry, it can be used as an acidity regulator or food processing aid (such as handling cocoa beans and adjusting the pH of dough), but the dosage must be strictly controlled. In addition, sodium hydroxide is often used in water treatment to remove heavy metal ions from water and is also used as a standard reagent in laboratories. Due to its strong corrosiveness, protective equipment should be worn when in contact to avoid direct contact with skin and eyes. When stored, it should be sealed to prevent deliquescence and absorption of carbon dioxide from the air.

| Conclusion | Qualified | |
1.Preparation of chemical raw materials:
The electrolysis of brine to produce chlorine gas, hydrogen gas and caustic soda (chlor-alkali industry) is the foundation of modern chemical engineering.
It is used for manufacturing inorganic compounds such as soda ash (sodium carbonate), baking soda (sodium bicarbonate), and borax;
As an organic synthesis raw material, it participates in reactions such as ester hydrolysis and dehalogenation of halogenated hydrocarbons, and is used in the production of intermediates for detergents, pesticides and dyes.
2. Light Industry and Textile Industry:
Soap and detergent: Through saponification reaction, animal and vegetable oils are converted into sodium higher fatty acids (soap) and glycerol;
Papermaking and pulping: Dissolve lignin, separate cellulose to prepare pulp, and improve the whiteness and purity of paper;
Textile printing and dyeing: Remove grease, wax and natural impurities from fabrics (mercerization treatment), and serve as an auxiliary agent for dye fixation.
