Sodium nitrate solution is neutral, easy to decompose when heated, and has the function of combustion supporting and oxidation. Therefore, it has a wide range of applications and more functions. What is its main function?
Enamel industry is used as flux, oxidant and raw material for preparing enamel powder. Glass industry is used as decolorizer, defoamer, clarifier and oxidant for a variety of glass and products. Inorganic industry is used as decolorizing agent for molten caustic soda and manufacturing other nitrates. As a colorant in meat processing, food industry can prevent meat deterioration and play a role in seasoning. Chemical fertilizer industry is the speed fertilizer for acid soil, as well as root crops such as beet and radish. As a raw material for industrial production of picric acid dyes.
Jicheng industry is metal cleaning agent and ferrous metal bluing agent. The pharmaceutical industry is used as a medium for penicillin. The tobacco industry is used as a combustion promoter for tobacco. Used as a chemical reagent in analytical chemistry.
Chemically pure sodium nitrate can also be used for low chromate passivation of zinc coating and oxidation solution of magnesium alloy.
It can play a role in many industries. Therefore, it is more and more widely used. In addition to mastering the correct use method, enterprises should also pay attention to storing it in a cool and ventilated place because it has combustion supporting performance.
It is easily soluble in water, has simple production process, is not difficult to obtain raw materials and has a wide range of uses. In industry, it is usually prepared by the reaction of some compounds
1. Reaction between acid and metal oxide: reaction between dilute nitric acid and sodium oxide: it can also be prepared.
2. Acid base reaction: sodium hydroxide solution reacts with dilute nitric acid to form it and water.
3. Reaction between salt and acid: reaction between sodium carbonate and dilute nitric acid: form it, water and carbon dioxide.
4. Reaction between salt and salt: reaction between sodium chloride and silver nitrate: formation of precipitation between it and silver chloride.
Compared with other production processes, the method of preparing sodium nitrate by reaction of some compounds is simple, low cost, and will not produce some harmful substances in the production process, which is relatively safe.
