Sodium hydroxide, inorganic compound, chemical formulaNaOH, also known as caustic soda, caustic soda, solid soda, caustic soda, Caustic soda. Sodium hydroxide is highly alkaline and highly corrosive. It can be used as an acid neutralizer, masking agent, precipitant, precipitation masking agent, developer, saponification agent, peeling agent, detergent, etc. It has a wide range of uses.
Staff should take precautions to avoid accidental contact with skin and eyes , should be rinsed immediately with plenty of water. The working environment should have good ventilation conditions. The sodium hydroxide aqueous solution has a slippery feel and generates high heat when dissolved in water. Wear protective goggles and rubber gloves when operating, and be careful not to splash on the skin or eyes.
Application fields of caustic soda hydroxide
Sodium hydroxide is mainly used in papermaking, production of cellulose pulp, production of soap, synthetic detergents, synthetic fatty acids, and refining of animal and vegetable oils and fats. In the textile printing and dyeing industry, it is used as cotton desizing agent, scouring agent and mercerizing agent. The chemical industry is used to produce borax, sodium cyanide, formic acid, oxalic acid, phenol, etc. It is used in the petroleum industry to refine petroleum products and in oil field drilling muds. It is also used in the surface treatment of aluminum oxide, metallic zinc and metallic copper, as well as in glass, enamel, tanning, medicine, dyes and pesticides. Food-grade products are used as acid neutralizers in the food industry, as peeling agents for citrus and peaches, and as detergents for empty bottles and cans, as well as decolorizing and deodorizing agents.
When sodium hydroxide is used as a basic reagent, it can be used as a neutralizing agent, a masking agent, a precipitant, a precipitation masking agent, an absorbent for a small amount of carbon dioxide and water, and a chromogenic agent for the determination of ketosterols by thin layer analysis. It is widely used Used in the manufacture of various sodium salts, soaps, paper pulp, finishing cotton fabrics, silk, viscose fibers, recycling of rubber products, metal cleaning, electroplating, bleaching, etc.
In cosmetic creams, saponified sodium hydroxide and stearic acid act as emulsifiers and are used to make creams, shampoos, etc.
is mainly used in the field of water treatment ForPH value adjustment.
