Sodium nitrate can absorb heat when dissolved in water.
Heated to above 380 ℃ is decomposed into sodium nitrite and oxygen, emit nitrogen and oxygen when 400 a 600 ℃, 700 ℃ when the release of nitric oxide, 775 ~ 865 ℃ when only a small amount of nitrogen dioxide and nitrous oxide generated.
Hot with sulfuric acid, then generate nitric acid and sodium bisulfate.
Inorganic industry as decoloring agent for molten caustic soda and sodium nitrate used in the manufacture of other nitrates.
send lubricious agent used in meat processing, food industry can prevent meat metamorphism, and flavoring.
Used as a fertilizer industry for acidic soil organic fertilizer, especially for root crops, such as beet, carrot, etc.
Dyestuff industry used as production picric acid and raw materials.
that is appropriate of Shanghai xin chemical industry to introduce the properties of sodium nitrate solution absorption of heat, more consultation, can contact Shanghai xin chemical co. , LTD.
