Description :
Tasted is a colorless transparent crystal. Soluble in water, and at the same time, strong exothermic. And soluble in ethanol and glycerin; Not soluble in acetone, ethyl ether. Dew in the air, and finally will be completely dissolved into the solution. Melting point: 681 ° C (lit.) boiling point: 145 ° C density: 1.515 g/mL at twenty ° C flash point: 176-178 ° C.
USES :
Basic chemical raw materials, used for high purity reagent, widely used in chemical industry, metallurgy, paper making, oil, textile and daily chemical and other departments. 2 is used for making paper, cellulose pulp production; Used for soap, synthetic detergent, synthetic fatty acid production as well as the animal and plant oil refining. Textile printing and dyeing industry used for cotton desizing agent, scouring agent and SiGuangJi. Chemical industry for the production of sodium borate, sodium cyanide, formic acid, oxalic acid, phenol, etc. The oil industry for refined oil products, and used in oil field drilling mud in. Also used in the production of alumina, metal zinc and copper metal surface treatment and glass, enamel, leather, medicine, dye and pesticide. Food grade products in the food industry used as acid neutralizing agent, can make citrus, peach, peeling agent, and decoloring agent, deodorants.3 used for analysis reagent, saponification agent, a small amount of carbon dioxide and water absorption agent, also used in the manufacture of sodium used for textile, printing and dyeing, enamel, papermaking, synthetic detergent, pesticide, metallurgy, food industry, rubber industry five basic chemical raw materials, widely used in chemical industry, metallurgy, paper making, oil, textile and daily chemical and other departments in the analysis used as acid is mainly used for calibration and mucus method rayon, synthetic fiber, dye intermediates, rubber regeneration, papermarking, soap, and other leather, acid neutralizing agent, can be used for fruit processing to skin, also can be used as empty bottles, cans and other containers of detergent, according to production need to moderate use.
