Ammonium chloride Usage And Synthesis
descriptionAmmonium 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 ammonia but insoluble in acetone 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 ammonia 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 ammonia and hydrogen chloride or ammonia and hydrochloric acid (reaction equation: NH3 + HCl → NH4Cl). When heated, it will decompose into hydrogen chloride and ammonia reaction (equation: NH4Cl → NH3 + HCl) and the reaction is only to the right if the container is open system.

Chemical propertiesAmmonium 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.
UsesAmmonium 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.

Chemical PropertiesAmmonium chloride,Nl4CI, also known as ammoniae, salmiai,and ammonium nituriate,is a white crystalline solid. It is soluble in water, aqueous solutionsof ammonia, and is slightly soluble in methyl alcohol. Ammonium chloride is found in natureas a sublimation productof volcanic activity, or is produced by neutralizing HCI(either in liquid or gaseousphase) with NH3 gas or liquid NH40H then evaporating the excess H20. The salt decomposes at350°C and sublimes under controlled conditions at 520 °C. Ammoniumchlorideis used as an electrolyte in dry cell batteries,as a fluxfor soldering, tinningandgalvanizing, andas a processing ingredientin textile printing and hide tanning. Use as a source of nitrogen for fertilizersis limited because of the possible build up of damaging chloride residuals in the soil.

OccurrenceAmmonium chloride occurs in nature in crevices near volcanoes. Also, it is found in smoke when burning dry camel or donkey dung as fuel. Important applications of this compound include the manufacture of dry cells for batteries; as a metal cleaner in soldering; as a flux in tin coating and galvanizing; in fertilizers; in pharmaceutical applications as a diuretic, or diaphoretic expectorant; and as an analytical standard in ammonia analysis. Also, it is used in freezing mixtures; washing powders; lustering cotton; in safety explosives and in dyeing and tanning.
UsesAmmonium Chloride is a dough conditioner and yeast food that exists as colorless crystals or white crystalline powder. approximately 30–38 g dissolves in water at 25°c. the ph of a 1% solution at 25°c is 5.2. it is used as a dough strengthener and flavor enhancer in baked goods and as a nitrogen source for yeast fermentation. it is also used in condiments and relishes. another term for the salt is ammonium muriate.
ApplicationAmmonium chloride is also known as sal ammoniac. white crystals made by ammonia salts acting upon hydrochloric acid followed by crystallization. It was used as a halide in many processes, including the salted paper, albumen paper, albumen opaltype, and gelatin emulsion processes. ammonium chloride is also used as a thickener and as an additive in non-alcoholic toners. According to cosmetic formulators, the ammonium component provides the tingling or stinging sensation that some people associate with toners or aftershaves, and which, in regular toners, is usually provided by the alcohol content. Ammonium chloride’s use is the result of preference in formulation feel.
PreparationAmmonium chloride is prepared commercially by reacting ammonia with hydrochloric acid. It may be prepared by fractional crystallization from a solution containing ammonium sulphate and sodium chloride or ammonium carbonate and calcium chloride. Because of it sease of preparation it can be manufacture dindustrially along side any plant that uses or produces ammonia. Ammonium chloride is used in dry cells, metal finishing, and in the preparation of cotton for dyeing and printing.
DefinitionChEBI: Ammonium chloride is an inorganic chloride having ammonium as the counterion. It has a role as a ferroptosis inhibitor. It is an inorganic chloride and an ammonium salt.
General DescriptionAmmonium chloride is a white crystalline solid. Ammonium chloride is soluble in water(37%). The primary hazard is the threat posed to the environment. Immediate steps should be taken to limit its spread to the environment. Ammonium chloride is used to make other ammonium compounds, as a soldering flux, as a fertilizer, and for many other uses.
Air & Water ReactionsSoluble in water. Slowly releases hydrogen chloride [USCG, 1999].
Reactivity ProfileAcidic salts, such as Ammonium chloride , are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.
HazardEye and upper respiratory tract irritant.
Health HazardInhalation of fumes irritates respiratory passages. Ingestion irritates mouth and stomach. Fumes are irritating to eyes. Contact with skin may cause irritation.
Flammability and ExplosibilityNon flammable
Agricultural UsesAmmonium chloride, like all other ammonium salts, is used as a fertilizer. It contains 24 to 26% nitrogen and is available as white crystals or granules. A coarse form of this fertilizer is preferred to the powdered form for direct application. It is used either directly for fertilization or in a variety of compound fertilizers, such as ammonium phosphate chloride or ammonium potassium chloride or in combination with urea or ammonium sulphate.
As a fertilizer, ammonium chloride has an advantage in that it contains 26% nitrogen, which is higher than that found in ammonium sulphate (20.5%). In terms of per unit cost of nitrogen, ammonium chloride is relatively cheaper than ammonium sulphate and has some agronomic advantages for rice. Nitrification of ammonium chloride is less rapid than that of urea or ammonium sulphate. Therefore, nitrogen losses are lower and yields, higher. It is a good source of nitrogen for cotton, rice, wheat, barley, maize, sorghum, sugar cane and fiber crops.
However, ammonium chloride is a highly acid forming fertilizer and the amount of calcium carbonate required to neutralize the acidity is more than the fertilizer itself, Further, it has a lower nitrogen content and a higher chloride content compared to urea and ammonium nitrate, making it harmful to some plants. It is not ideal for grapes, chilies, potatoes and tobacco as the added chlorine affects the quality and storability of these crops.
Biochem/physiol ActionsAmmonium chloride is one of the three principal components of the nitrogen cycle. Ammonium chloride administration promotes creatinine and urea clearance andinduces metabolic acidosis in mice. Excess of ammonium chloride inhibits Kreb′s pathway in brain and depletes ATP in astrocytes. Ammonium chloride inhibits acidification in the endosome-lysosome system. Ammonium chloride is a hemolysing agent used for the lysis of erythrocytes.
SafetyAmmonium chloride is used in oral pharmaceutical formulations. The pure form of ammonium chloride is toxic by SC, IV, and IM routes, and moderately toxic by other routes. Potential symptoms of overexposure to fumes are irritation of eyes, skin, respiratory system: cough, dyspnea, and pulmonary sensitization. Ammonium salts are an irritant to the gastric mucosa and may induce nausea and vomiting.
LD50 (mouse, IP): 1.44 g/kg
LD50 (mouse, oral): 1.3 g/kg
LD50 (rat, IM): 0.03 g/kg
LD50 (rat, oral): 1.65 g/kg
Potential ExposureAmmonium chloride is used as an industrial chemical, pharmaceutical, and veterinary drug; to make dry batteries; in galvanizing; as a soldering flux.
Veterinary Drugs and TreatmentsThe veterinary indications for ammonium chloride are as a urinary acidifying agent to help prevent and dissolve certain types of uroliths (e.g., struvite), to enhance renal excretion of some types of toxins (e.g., strontium, strychnine) or drugs (e.g., quinidine), or to enhance the efficacy of certain antimicrobials (e.g., chlortetracycline, methenamine mandelate, nitrofurantoin, oxytetracycline, penicillin G or tetracycline) when treating urinary tract infections. Ammonium chloride has also been used intravenously for the rapid correction of metabolic alkalosis.
Because of changes in feline diets to restrict struvite and as struvite therapeutic diets (e.g., s/d) cause aciduria, ammonium chloride is not commonly recommended for struvite uroliths in cats.
storageAmmonium chloride is chemically stable. It decomposes completely at 3388℃ to form ammonia and hydrochloric acid. Store in airtight containers in a cool, dry place.
