Sodium hydroxide has a very wide range of uses, in chemical experiments, in addition to being used as a reagent, because it has a strong hygroscopic property, can also be used as an alkaline desiccant. Caustic soda is widely used in the national economy and is needed in many industrial sectors. The sector that uses caustic soda the most is the manufacture of chemicals, followed by the manufacture of paper, aluminium, tungsten, rayon, cotton and soap. In addition, in the production of dyes, plastics, pharmaceutical and organic intermediates, the regeneration of old rubber, metal sodium, water electrolysis and inorganic salt production, to make borax, chromium salt, manganese salt, phosphate, etc., also want to use a lot of caustic soda. Sodium hydroxide for industrial use should meet the national standard GB209-2006; Industrial ion exchange membrane method of sodium hydroxide should conform to the national standard GB/T11199-89; Sodium hydroxide for chemical fiber should meet the national standard GB11212-89; Edible sodium hydroxide should meet the national standard GB5175-85. In industry, sodium hydroxide is usually called caustic soda, or caustic soda, sodium Chemicalbook. This is because the more concentrated sodium hydroxide solution splashed on the skin, will erode the epidermal, causing burns. It is protein-soluble and is strongly irritating and corrosive (alkali burns are less likely to heal than acid burns due to its protein-soluble effect). The corneal epithelium can be damaged by dropping 0.02% solution into rabbit eyes. Intraperitoneal LD50:40mg/kg in mice, oral LDLo in rabbits :500mg/kg. Dust irritates eyes and respiratory tract, corrodes nasal septum; Splash to the skin, especially to the mucosa, can produce soft scab, and can penetrate deep tissue, burn scar; Splash into the eye, not only damage the cornea, but also can make the deep tissue injury of the eye, serious can cause blindness; Misingestion can cause digestive tract burns, colic, mucosal erosion, vomiting bloody stomach contents, bloody diarrhea, sometimes hoarseness, dysphagia, shock, digestive tract perforation, and gastrointestinal stenosis in the later stage. Due to strong alkalinity, it can cause pollution to water, so attention should be paid to plants and aquatic organisms.
