2.Caustic soda Molecular formula: NaOH. Commercially available are solid caustic soda flake caustic soda and liquid caustic soda two kinds: pure white solid caustic soda, caustic soda flakes loaded with blocks, rod-like caustic soda, granular caustic soda, crisp; pure liquid (caustic soda) for colorless transparent liquid. Of solid caustic soda has very strong hygroscopicity. Soluble in water, dissolved when the heat, alkaline aqueous solution, there are creamy feel; soluble in ethanol and glycerin; do not dissolve in acetone, ethyl ether. Highly corrosive, for fiber, skin, glass, ceramics are corrosion. With metal aluminum and zinc, boron and silicon and other non-metallic reaction to release hydrogen; with chlorine, bromine, iodine and other halogen disproportionation reaction; with the acids and the role played in the formation of salt and water. 3. Caustic soda, the main uses: mainly used in the production of paper pulp cellulose, for soap synthetic detergent, synthetic fatty acid production and refining plant and animal oils and fats. Organization of printing and dyeing industry as cotton desizing agent, scouring agent and mercerized agents, the chemical industry for the production of boric acid, sodium chloride, formic acid, oxalic acid, phenol and so on. Petroleum industry for refined petroleum products, and for oil drilling mud, it is also used to produce alumina, metal zinc and copper surface treatment of metal and glass, Tong porcelain, leather, pharmaceuticals, dyes and pesticides. Food and products in the food industry used as acid-A agent, can be used for citrus, peaches, peeled agents such as bleaching agents, deodorizing agents. 4. Caustic soda products widely used, is the most basic chemical raw materials; widely used in chemical industry, metallurgy, paper, petroleum, textile and chemical sectors such as daily
      (1) manufacturing soap. The main components of soap, the sodium salt of higher fatty acids, usually oil and caustic soda, caustic soda, sodium hydroxide as raw materials made through the saponification reaction.
     (2) of refined petroleum. By the sulfuric acid washing of petroleum products also contain a number of acidic substances, must use caustic soda, caustic soda, sodium hydroxide solution, washed, and then by washing in order to obtain refined products.
      (3) paper. Paper-making raw materials are wood or grass-like plants, except where these plants contain cellulose, but also contains a considerable number of non-cellulose (lignin, gums, etc.). Add dilute caustic soda, caustic soda, sodium hydroxide solution can be dissolved in the separation of non-cellulose components, thus the system can be mainly composed of cellulose pulp.
    (4) textiles. Man-made fibers such as rayon, fake fur, artificial silk, etc., mostly viscose fibers, which is cellulose (such as the pulp), caustic soda, sodium hydroxide, carbon disulfide (CS2) as the raw material made of viscose liquid, by spraying silk, condensation and obtained.
   (5) printing and dyeing. Cotton with caustic soda, caustic soda solution after treatment can remove the covering the cotton on the wax, grease, starch and other substances at the same time can increase the mercerized fabric color, so that more uniform dyeing.
