Product Description
Product Description
Sodium hydroxide, also known as caustic soda and caustic soda, with the chemical formula NaOH, is a strong alkali with high corrosiveness, generally white flakes or granules, which can be miscible with water to form an alkaline solution, and can also be dissolved in methanol and ethanol. This alkaline substance is deliquescent and absorbs chemical vapor from the air, as well as acidic gases such as carbon dioxide. Sodium hydroxide is one of the commonly used chemicals. It is used in a wide range of applications and is essential for many industrial processes: it is often used in the manufacture of wood pulp and paper, textiles, soaps and other cleaning agents, and is also used in household alkaline drainage products.
Purpose
Sodium hydroxide is widely used, in chemical experiments, in addition to being used as a reagent, because it has strong hygroscopicity, it can also be used as an alkaline desiccant. Caustic soda is widely used in the national economy, and caustic soda is required in many industrial sectors. The largest use of caustic soda is in the manufacture of chemicals, followed by paper, aluminum, tungsten, rayon, rayon and soap. In addition, a large amount of caustic soda is also used in the production of dyes, plastics, pharmaceuticals and organic intermediates, the regeneration of old rubber, the electrolysis of metal sodium and water, and the production of inorganic salts, and the production of borax, chromium salts, manganates, phosphates, etc. Sodium hydroxide for industrial use shall comply with the national standard GB209-2006; Sodium hydroxide by ion exchange membrane for industrial use shall comply with the national standard GB/T11199-89; Sodium hydroxide for chemical fiber should meet the national standard GB11212-89; Edible sodium hydroxide should comply with the national standard GB5175-85. In industry, sodium hydroxide is commonly called caustic soda, or caustic soda, caustic soda Chemicalbook. This is because a concentrated solution of sodium hydroxide splashes on the skin, which can corrode the epidermis and cause burns. It has a solubilizing effect on proteins, is strongly irritating and corrosive (due to its solubilizing effect on proteins, alkali burns are less likely to heal than acid burns). Drip into rabbit eye with 0.02% solution can cause corneal epithelial damage. Intraperitoneal LD50 in mice: 40mg/kg, oral LDLo in rabbit: 500mg/kg. Dust irritates the eyes and respiratory tract and erodes the nasal septum; Splashing on the skin, especially mucous membranes, can produce a soft crust and can penetrate deep tissues, leaving scars after burns; Splashing into the eye not only damages the cornea, but also damages the deep tissues of the eye, and in severe cases, it can cause blindness; Accidental ingestion can cause gastrointestinal burns, colic, mucosal erosion, vomiting of bloody gastric contents, bloody diarrhea, sometimes hoarseness, dysphagia, shock, gastrointestinal perforation, and later gastrointestinal stricture. Due to the strong alkalinity, it can cause pollution to the water body, and attention should be paid to plants and aquatic organisms.
Application
Sodium hydroxide can be used in the production of papermaking and cellulose pulp; It is used in the production of soaps, synthetic detergents, synthetic fatty acids and the refining of animal and vegetable fats and fats. In the textile printing and dyeing industry, it is used as a desizing agent, a cooking agent and a mercerizing agent for cotton cloth. It is used in the chemical industry to produce borax, sodium cyanide, formic acid, oxalic acid, phenol, etc. It is used in the petroleum industry to refine Chemicalbook petroleum products and is used in oilfield drilling muds. In addition, caustic soda is used in the surface treatment of alumina, zinc and copper as well as in glass, enamel, tanning, medicine, dyes and pesticides. Food-grade products are used as acid neutralizers in the food industry, and can be used as peeling agents for citrus and peaches, as well as decolorizers and deodorants.
