NaOH Caustic Soda Sodium Hydroxide Inorganic Compound Strong Corrosiveness 25 KG / BAG

Sodium hydroxide, with the chemical formula NaOH and a relative molecular mass of 39.9970, is an inorganic compound that is highly alkaline and extremely corrosive. It can be used as an acid neutralizer, a complex masking agent, a precipitating agent, a color developer, a saponifying agent, a peeling agent, a detergent, etc. Its applications are extensive.

Sodium hydroxide has a corrosive effect on fibers, skin, glass, ceramics, etc. When dissolved or diluted as a concentrated solution, it releases heat. Neutralization reactions with inorganic acids can also generate a large amount of heat and form corresponding salts. It reacts with metals such as aluminium and zinc, and non-metals such as boron and silicon to release hydrogen. It undergoes disproportionation reactions with halogens such as chlorine, bromine and iodine. It can precipitate metal ions from aqueous solutions to form hydroxides. The principle of removing oil stains from fabrics is to make oils undergo saponification reactions and generate sodium salts and alcohols of corresponding organic acids.

1. It is used in the production of papermaking and cellulose pulp. It is used in the production of soap, synthetic detergents, synthetic fatty acids and the refining of animal and vegetable oils.

2. In the textile printing and dyeing industry, it is used as a desizing agent, scouring agent and mercerizing agent for cotton fabrics.

3. In the chemical industry, it is used to produce borax, sodium cyanide, formic acid, oxalic acid, phenol, etc. The petroleum industry uses it to refine petroleum products and it is also used in oilfield drilling mud.

4. It is also used in the production of alumina, surface treatment of metallic zinc and copper, as well as in the fields of glass, enamel, leather making, medicine, dyes and pesticides.

5. Food-grade products are used as acid neutralizers in the food industry. They can also be used as peelers for citrus fruits, peaches, etc., as detergents for empty bottles, cans and other containers, as well as decolorizing and deodorizing agents.

6. Widely used basic analytical reagents. It is widely used in papermaking, chemical engineering, printing and dyeing, medicine, metallurgy (aluminum smelting), chemical fiber, electroplating, water treatment, tail gas treatment, etc.

7. It is used in the preparation of sodium salts and as a saponification agent. It is used for manufacturing various sodium salts, soaps, pulp, finishing cotton fabrics, silk, viscose fibers, recycling rubber products, metal cleaning, electroplating, bleaching, etc.

8. In cosmetic creams and ointments, this product saponizes with stearic acid and others to act as an emulsifier, used in the production of cold creams, shampoos, etc.
