Ammonium chloride Usage And Synthesis

description	Ammonium chloride (referred to as "chloramine", also known as halogen sand, chemical formula: NH4Cl) is colorless cubic crystal or white crystalline powder. It tastes salty and slightly bitter and belongs to acid salt. Its relative density is 1.527. It is soluble in water, ethanol and liquid  but insble in and ether. The aqueous solution is weakly acidic, and its acidity is enhanced while heating. When heated to 100 ° C, it begins to significantly volatilize, and when heated to 337.8  ° C, it will dissociate into ammoa and hydrogen chloride, which, on cold exposure, will re-combine to produce small particles of ammonium chloride and white smoke that is not easy to sink and very difficult to be dissolved in water. When heated to 350 ° C ,it will sublimate and when 520 ° C, it will boil. Its moisture absorption is small, and in the wet rainy weather can absorb moisture to cake. For the ferrous metals and other metals, it is corrosive, which, in particular, has greater corrosion of copper but no corrosion of pig iron. Ammonium chloride can be obtained from the neutralization reaction of aonia and hydrogen chloride or ammia and (reaction equation: NH3 + HCl → NH4Cl). When heated, it will decompose into hydrogen chloride and amnia reaction (equation: NH4Cl → NH3 + HCl) and the reaction is only to the right if the container is open system. ammonium chloride powder
Chemical properties	Ammonium chloride NH4Cl (also called sal ammoniac) is a colourless crystal or white granular powder that dissolves easily in water.It is odourless and has a salty and bitter taste. It sublimes on heating to form ammonia and hydrogen chloride (gas). It is commonly used in the baked goods industry, as a functional salt and as a dough improver for yeasts.It gives the dough good elasticity,extensibility, and machinability, producing breads with good quality characteristics in terms of volume,colour, aroma, texture,and elasticity.Ammonium chloride is considered safe in small amounts. The Us Food and Drug Administration (FDA) granted ammonium hydroxide status as a GRAS, or Generally Recognized as Safe, substance in 1974 and it is also recognised as a food additive in the EU.
Uses	Ammonium chloride is mainly used for dry batteries, storage batteries, ammonium salts, tanning, plating, medicine, photography, electrodes, adhesives, etc. Ammonium chloride is also an available nitrogen chemical fertilizer whose nitrogen content is 24% to 25%. It is a physiological acidic fertilizer and suitable for wheat, rice, corn, rapeseed and other crops. It have the effects of enhancing fiber toughness and tension and improving quality especially for cotton and linen crops. However, due to the nature of ammonium chloride, if the application is not right, it will bring some adverse effects to soil and crops. Technical conditions: the implementation of the People's Republic of China national standard GB-2946-82. 1. Appearance: white crystal 2. ammonium chloride content (dry basis) ≥ 99.3% 3. moisture content ≤1.0% 4. sodium chloride content (dry basis) ≤0.2% 5. iron content ≤0.001% 6. heavy metal content (in terms of Pb) ≤0.0005% 7. water insoluble content ≤0.02% 8. sulfate content (in terms of SO42-) ≤0.02% 9. pH: 4.2-5.8
Production method	(1) Recrystallization method: the industrial ammonium chloride is added into the dissolver which has been filled with distilled water, and dissolved by heating. The obtained solvents is purified by arsenic removal and heavy metal removal, and then filtered, cooled for crystallization, centrifuged and dried. Finally the chemical ammonium chloride is finished. (2) Metathesis method: the mother liquor of ammonium chloride is added to reactor and heated to 105 ° C. Add ammonium sulfate and salt under stirring and proceed metathesis reaction at 117 ° C, resulting in forming ammonium chloride solution and sodium sulfate crystallization. The obtained mixture is then filtrated and separated to remove sulfuric acid Sodium. Add arsenic removal and heavy metal removal to the filtrate and filtrate to remove arsenic, heavy metals and other impurities. The filtrate is sent to a cooling crystallizer and is cooled to 32-35 ºC to precipitate the crystals. The crystals are filtered and washed with ammonium chloride solution, and then are dehydrated by centrifugal separation and dried to obtain finished edible ammonium chloride.  Reaction formula: (NH4) 2SO4 + 2NaCl→2NH4Cl + Na2SO4 Recrystallization method: the industrial ammonium chloride is added into the dissolver which has been filled with distilled water, and dissolved by heating. The obtained solvents is purified by arsenic removal and heavy metal removal, and then filtered, cooled for crystallization, centrifuged and dried. Finally the edible ammonium chloride is finished. (3) The mother liquor was filtrated by associated alkali method and cooled for crystallization, and then add salt powder to salt out the product. It can also be obtained by derived replacement reaction of ammonium sulfate and calcium chloride in aqueous solution. (4) Gas-liquid phase synthesis: hydrogen chloride gas is added from the bottom of the turbulence absorption tower and then contact with the circulating mother liquor flowing from overhead spray to generate chloride mother liquor containing saturated ammonium chloride. Chloride mother liquor then flows into the reactor and react with   ammonia gas to form a saturated ammonium chloride solution. The obtained solvents are sent to the cooling crystallizer and cooled to 30~45 ° C to precipitate supersaturated ammonium chloride crystals. The ammonium chloride solution in the upper part of the crystallizer is sent to the air cooler for cooling and circulating to the crystallizer; the crystal slurry in the lower part of the crystallizer is thickened by thickening thickener and centrifuged for separation to obtain ammonium chloride. Reaction formula: HCl + NH3 → NH4Cl The mother liquor separated by centrifugation is sent to the turbulent absorption tower for recycling. Metathesis method: the mother liquor of ammonium chloride is added to reactor and heated to 105 ° C. Add ammonium sulfate and salt under stirring and proceed metathesis reaction at 117 ° C, resulting in forming ammonium chloride solution and sodium sulfate crystals. The obtained mixture is then filtrated to remove sulfuric acid Sodium and the filtrate is sent to cooling crystallizer and cooled to 32 to 35 ºC for crystallization. Then the crystals of ammonium chloride is obtained by filtration and  respectively washed by 4 different concentrations (15~17°Bé,11~12°Bé,10°Bé,9.5~10°Bé) of ammonium chloride solution, controlling Fe < 0.008%, SO42-< 0.001%. After elution to qualified, use ammonium chloride solution to remake the crystals into slurry, put into the centrifuge for separation and dehydration. And then dry by hot air and obtain the industrial ammonium chloride products. Reaction formula: 2NaCl + (NH4) 2SO4 → 2NH4Cl + Na2SO4 The mother liquor is sent to the metathesis reactor for recycling. The separated sodium sulfate is filtered to produce sodium sulfate. The crude ammonium chloride is added into the dissolving device, dissolved in the steam and filtered. The filtrate is cooled for crystallization, centrifugalized and dried to obtain the finished products of industrial ammonium chloride. The mother liquor from the centrifugal separation is returned to the dissolver for use.
