Background

Potassium nitrate refers to nitrate of potassium, commonly called potassium nitrate or soil nitrate, is colorless transparent orthorhombic crystal or rhombic crystal or white powder, and has no odor, no toxicity, salty taste and cool feeling. The water-soluble polyurethane has the advantages of small moisture absorption in air, difficult agglomeration, easy water solubility and rapid increase of the solubility along with the temperature rise. Can be dissolved in liquid ammonia and glycerin, and can not be dissolved in absolute ethyl alcohol and ethyl ether, and the potassium nitrate is a strong oxidant, and can be contacted with organic matter to cause combustion and explosion. Therefore, the potassium nitrate should be stored in a cool and dry place away from the fire and heat sources. The materials are not mixed with reducing agent, acid, easily combustible substance and metal powder.

Because the solubility of potassium nitrate is greatly changed along with the temperature, and the solubility is smaller at low temperature, the cooling crystallization (cooling of a hot saturated solution) is the best method, the principle of the cooling crystallization is that the temperature is reduced, the solubility of a substance is reduced, the solution is saturated, and redundant solute which cannot be dissolved can be separated out. For example, alkali removal in winter is the reason (by using temperature change). The principle of evaporative crystallization is that under the condition of constant temperature or before and after evaporation, the temperature is unchanged, the solubility is unchanged, the water content is reduced, and the solution is saturated, namely redundant solute is separated out. For example, the salt is sun-dried in the salt lake in summer, the temperature is reduced for crystallization, the solution is heated and concentrated to obtain a hot saturated solution, then the hot saturated solution is filtered to remove insoluble impurities, the crystals are cooled for crystallization and filtered, the obtained crystals can contain other impurities, and the crystals are recrystallized if further purification is needed.
