Uses and synthesis of Ammonium chloride Powder

Ammonium chloride Powder is colorless cubic crystal or white crystalline powder. It has a salty, cool and slightly bitter taste, and is an acid salt. Relative density 1.527.

Ammonium chloride CAS 12125-02-9 is soluble in water and ethanol, soluble in liquid ammonia, insoluble in acetone and ether. Aqueous solution is weakly acidic, and the acidity increases when heated. When heated to 100 ° C began to volatilize significantly, 337.8 ° C dissociated into ammonia and hydrogen chloride, cold and re-combined to generate very small particles of ammonium chloride and white smoke, not easy to sink, but also not easy to re-dissolve in water.Ammonium chloride CAS 12125-02-9 sublimation when heated to 350 ° C, boiling point 520 ° C. Hygroscopicity is small, but the humidity is low, but the humidity is low, but it is not soluble in water and ethanol, acetone and ether.

Ammonium chloride Raw Materials is corrosive to ferrous metals and other metals, especially more corrosive to copper, no corrosive effect on pig iron.

production methodprocess of Ammonium chloride Powder

Recrystallization method will be added to the industrial ammonium chloride has been filled with distilled water in the dissolver, through the heating to make it dissolve, after arsenic and heavy metal purification treatment, filtration, cooling crystallization, centrifugal separation, drying, the production of Ammonium chloride Powder

Complex decomposition method will be added to the mother liquor of ammonium chloride reactor heated to 105 ℃, add ammonium sulfate and salt under stirring, at 117 ℃ for the complex decomposition reaction, the generation of ammonium chloride solution and sodium sulfate crystals, after filtration, separation and removal of sodium sulfate, add arsenic and heavy metal removal agent to the filtrate solution purification, filtration, removal of arsenic and heavy metals and other impurities. The filtrate will be sent to the cooling crystallizer, cooled to 32 ~ 35 ℃ precipitation of crystals, filtration, the crystals with ammonium chloride solution for washing qualified, centrifugal separation dehydration, drying, the preparation of edible ammonium chloride finished products. Its (NH4)2SO4 + 2NaCl → 2NH4Cl + Na2SO4 recrystallization method will be added to the industrial-grade ammonium chloride has been filled with distilled water in the dissolver, by heating to make it dissolve, adding arsenic and heavy metal removal agent for solution purification, filtration, removal of arsenic and heavy metals and other impurities, the filtrate cooled crystallization, centrifugal separation, drying, the production of edible Ammonium chloride Powder.

It is obtained by cooling and crystallizing the mother liquor filtered out by the combined alkali method, and then adding fine salt powder for salting out. It is obtained by replacing ammonium sulfate with calcium chloride in aqueous solution.

Gas-liquid phase synthesis method passes hydrogen chloride gas from the bottom of the turbulent flow absorption tower, contacting with the circulating mother liquor sprayed at the top of the tower, generating the saturated hydrogen chloride mother liquor of ammonium chloride flowing into the reactor, neutralizing and reacting with the passed ammonia gas, generating a saturated solution of ammonium chloride. Sent to the cooling crystallizer, after cooling to 30 ~ 45 ℃, precipitation of supersaturated ammonium chloride crystals. The ammonium chloride solution in the upper part of the crystallizer is sent to the air cooler to cool and circulate to the crystallizer; the lower part of the crystal slurry is thickened by the thickener and then centrifuged to produce finished ammonium chloride products. The mother liquor of HCl+NH3→NH4Cl separated by centrifugation is sent to turbulent flow absorption tower for recycling. Complex decomposition method firstly, the mother liquor of ammonium chloride is added into the reactor and heated to 105°C, then ammonium sulfate and table salt are added, and the complex decomposition reaction is carried out at 117°C, which generates ammonium chloride solution and sodium sulfate crystals, and the sodium sulfate is removed by filtration and separation, and the saturated solution of ammonium chloride is sent to the cooled crystallizer, which is cooled to 32-35°C for precipitation of crystals, filtered, and the crystals are separated by four different concentrations (15-17°Bé, 11 ~ 12 ° Bé, 10 ° Bé, 9.5 ~ 10 ° Bé) of ammonium chloride solution for washing, control Fe <0.008%, SO42- <0.001%, washing to qualified, and then ammonium chloride solution to re-modulate the crystals into a slurry, sent to centrifugal separation and dehydration, and then drying by the hot air, the production of finished products of industrial ammonium chloride. Its 2NaCl+(NH4)2SO4→2NH4Cl+Na2SO4 mother liquor is sent to the compound decomposition reactor for recycling. The filter-separated sodium sulfate is used for the production of methanol. Recrystallization method adds crude ammonium chloride into the dissolver, passes through the steam to dissolve, after filtration, the filtrate is cooled and crystallized, centrifugally separated and dried to produce finished industrial ammonium chloride. The mother liquor separated by centrifugation is returned to the dissolver for use.
