Alkali price, caustic soda use, caustic soda manufacturer, sodium hydroxide price, sodium hydroxide content, sodium hydroxide wholesale, sodium hydroxide use, sodium hydroxide manufacturer, caustic soda price, caustic soda use, caustic soda manufacturer, caustic soda caustic soda wholesale, Caustic soda content, caustic soda (scientific name is sodium hydroxide) is a soluble strong alkali. Soda ash (scientific name: sodium carbonate) is actually a salt. Due to its hydrolysis in water, the solution becomes alkaline. And because it has some similar properties to caustic soda, it is juxtaposed with caustic soda and is called "two" in industry. Alkali”. Both caustic soda and soda ash are easily soluble in water, are strongly alkaline, and can provide Na+ ions. These properties make them widely used in various sectors such as soap making, textile, printing and dyeing, bleaching, papermaking, refined petroleum metallurgy and other chemical industries. Ordinary soap is the sodium salt of higher fatty acids, which is generally made by saponifying oil with a slight excess of caustic soda. If fatty acids are used directly as raw materials, soda ash can be used instead of caustic soda to make soap. In the printing, dyeing and textile industries, a large amount of lye is also used to remove grease from cotton yarn, wool, etc. Caustic soda or soda ash is also required for the production of man-made fibers. For example, to make viscose fiber, you must first impregnate cellulose with 18-20% caustic soda solution (or soda ash solution) to turn it into alkali cellulose, then dry and crush the alkali cellulose, and finally use dilute alkali solution to remove sulfonate. When the acid salt is dissolved, a viscose liquid is obtained. After filtering and vacuuming (removing bubbles), it can be used for spinning. Caustic soda is also used to refine petroleum. In order to remove the colloid in the petroleum fraction, the petroleum fraction is generally concentrated - so that the colloid becomes an acid residue and precipitates. After pickling, the petroleum still contains acidic impurities such as phenol and naphthenic acid as well as excess sodium chloride. It must be washed with caustic soda solution and then washed with water to obtain refined petroleum products. In the paper industry, chemical treatment is first used to cook cellulose-containing raw materials (such as wood) with chemicals to make pulp. The so-called alkaline pulping is to use caustic soda or soda ash solution as the cooking liquid to remove lignin, carbohydrates and resins in the raw materials, and neutralize the organic acids in them, thus separating the cellulose. In the metallurgical industry, it is often necessary to convert the active ingredients in the ore into soluble sodium salts in order to remove insoluble impurities. Therefore, it is often necessary to add soda ash (which is also a flux) and sometimes caustic soda. For example, in the smelting process of aluminum, soda ash and caustic soda are used in the preparation of cryolite and the processing of bauxite. Another example is when smelting tungsten, the concentrate and soda ash are first roasted into soluble sodium tungstate, and then the powdered tungsten is obtained through acid precipitation, dehydration, reduction and other processes. In the chemical industry, caustic soda is used to produce alcohol and electrolyze water. Caustic soda or soda ash is used in the production of many inorganic salts, especially in the preparation of some sodium salts (such as borax, sodium silicate, sodium phosphate, sodium phosphate, sodium phosphate, etc.). Synthetic dyes, drugs and organic intermediates also use caustic soda or soda ash. Pure anhydrous sodium hydroxide is a white translucent, crystalline solid. Sodium hydroxide is very soluble in water. Its solubility increases with the increase of temperature, and it can release a lot of heat when it dissolves. Its solution has an astringent taste and a smooth feeling, and the solution is strongly alkaline and has all the properties of an alkali. There are two types of commercially available caustic soda: solid and liquid: pure solid caustic soda is white, available in block, flake, rod, and granular shapes, and is brittle; pure liquid caustic soda is a colorless and transparent liquid. Sodium hydroxide is also easily soluble in ---, glycerol; but insoluble in ---, ---, and liquid ammonia. It has a corrosive effect on fibers, skin, glass, ceramics, etc. It will release heat when dissolved or diluted with concentrated solutions; neutralization reactions with inorganic acids can also generate a large amount of heat and generate corresponding salts; with metal aluminum and zinc, non-metallic Reactions such as boron and silicon release hydrogen; disproportionation occurs with halogens such as chlorine, bromine, and iodine. It can precipitate metal ions from aqueous solutions into hydroxides; it can cause saponification of oils and generate corresponding sodium salts of organic acids and alcohols. This is the principle of removing oil stains on fabrics. Sodium hydroxide has a wide range of uses. In chemical experiments, in addition to being used as a reagent, it can also be used as an alkaline desiccant because of its strong hygroscopicity. Caustic soda is widely used in the national economy, and many industrial sectors require caustic soda. The sector that uses the most caustic soda is the manufacturing of chemicals, followed by paper making, aluminum smelting, tungsten smelting, rayon, rayon and soap manufacturing. In addition, it is used in the production of dyes, plastics, pharmaceuticals and organic intermediates, the regeneration of old rubber, the electrolysis of chemicals, water, and the production of inorganic salts.

In industry, sodium hydroxide is usually called caustic soda, or caustic soda and caustic soda. This is because concentrated sodium hydroxide solution splashed on the skin will corrode the epidermis and cause ---. It has a dissolving effect on proteins and is highly irritating and corrosive (due to its dissolving effect on proteins, alkalis are less likely to heal than acids). Instilling 0.02% solution into rabbit eyes can cause epithelial damage. Intraperitoneal LD50 in mice: 40 mg/kg, oral LDLO in rabbits: 500 mg/kg. Dust irritates the eyes and respiratory tract, and corrodes the nasal septum; splashing on the skin, especially mucous membranes, can produce soft scabs, and can penetrate into deep tissues, leaving scars after burns; splashing into the eyes not only damages the body, but can also cause Deep tissue damage in the eyes, severe cases may lead to blindness; ingestion may cause gastrointestinal burns, colic, mucosal erosion, vomiting bloody gastric contents, bloody diarrhea, and sometimes hoarseness, difficulty swallowing, ---, gastrointestinal perforation, Gastrointestinal stenosis may occur in the later stages. Due to its strong alkalinity, it can cause pollution to water bodies, so attention should be paid to plants and aquatic organisms. Regulations on the Safety Management of Chemical Hazardous Materials (issued by the State Council on February 17, 1987), "Regulations on the Safety Management of Chemical Hazardous Materials," and other regulations address the safe use, production, storage, transportation, loading and unloading of chemical dangerous goods.

Uses of sodium hydroxide (1) Refined petroleum . After washing, petroleum products still contain some acidic substances and must be washed with sodium hydroxide solution and then washed with water to obtain refined products. (2) Papermaking. The raw materials for papermaking are wood or grass plants. In addition to cellulose, these plants also contain a considerable amount of non-cellulose (lignin, gum, etc.). Adding dilute sodium hydroxide solution can dissolve and separate non-cellulose components, thereby producing pulp with cellulose as the main component. 3) Textile. Man-made fibers such as artificial cotton, artificial wool, rayon, etc. are mostly viscose fibers. They are made from cellulose (such as pulp), sodium hydroxide, and carbon disulfide as raw materials to make viscose liquid, which is then spun and condensed. have to. Baoding sodium hydroxide caustic soda tablets (4) printing and dyeing. After cotton fabrics are treated with caustic soda solution, the wax, grease, starch and other substances covering the cotton fabrics can be removed. At the same time, the mercerized color of the fabrics can be increased, making the dyeing more uniform. 5) Amend the soil with lime. In soil, organic acids are generated during the decomposition of organic matter, and the weathering of minerals may also produce acidic substances. In addition, the use of inorganic fertilizers such as ammonium chloride will also make the soil acidic. Applying an appropriate amount of lime can neutralize acidic substances in the soil, making the soil suitable for crop growth and promoting the reproduction of microorganisms. The increase in Ca2 in the soil can promote the coagulation of soil colloids, which is conducive to the formation of aggregates, and at the same time can provide the calcium needed for plant growth. (6) Make soap. The main component of soap is the sodium salt of higher fatty acids, which is usually made through saponification reaction using oil and sodium hydroxide as raw materials. Sodium hydroxide (naoh, commonly known as fire soda, caustic soda, caustic soda. It is called cox in Hong Kong) is a white crystal at room temperature and is highly corrosive. Easily soluble in water, its aqueous solution is strongly alkaline and can turn it red. Sodium hydroxide is a very commonly used alkali and one of the essential medicines in chemistry laboratories. Its solution can be used as a washing liquid. Chemically, it is a colorless and transparent sodium-alkali liquid. It is one of the strong bases and is easily dissolved in water.

Take --- as an example: Sodium hydroxide is also a good catalyst for many organic reactions. The most typical one is that the ester hydrolysis reaction proceeds completely and rapidly. This is why sodium hydroxide can burn the skin. Sodium hydroxide is one of the important raw materials for making soap. Add sodium hydroxide solution to the solution and the mixture will react and mix in the right proportion to become solid soap. This reaction also utilizes the principle of hydrolysis, and this type of ester hydrolysis catalyzed by naoh is called saponification reaction. Uses Sodium hydroxide is widely used in various production processes. In chemical production, sodium hydroxide provides an alkaline environment or serves as a catalyst. The dilute solution of naoh can be used as a washing liquid for household use. Baoding sodium hydroxide caustic soda tablets In food production, sodium hydroxide is sometimes used to process food. Sodium hydroxide is even an essential ingredient in a famous dish. Note that the use of sodium hydroxide at this time is strictly controlled; some unscrupulous vendors will use excessive amounts of sodium hydroxide to make the food more "pretty", but such food can cause illness. (1) Make soap. The main component of soap is the sodium salt of higher fatty acids, which is usually made through saponification reaction using oil and sodium hydroxide as raw materials. (2) Refined petroleum. Petroleum products still contain some acidic substances after being washed with sodium hydroxide.
