Usage areas:
Food industry:
Ammonium chloride, known with the code E510, is used in the food industry in the following areas:
Flavor Enhancer: Ammonium chloride is used as a food additive and most importantly to enhance the taste of licorice candies, especially salted licorice. It provides a salty taste without the need for sodium chloride (table salt). Salted licorice is popular in some regions such as Scandinavia and the Netherlands, and its distinctive salty and slightly tangy taste is caused by ammonium chloride.
Leavening Agent: In some traditional recipes, ammonium chloride has been used as a leavening agent in baking, especially in various types of cookies and crackers. It can release ammonia gas when heated, which can help create a lighter, crumblier texture in baked goods.
Food Preservation: Ammonium chloride has mild antimicrobial properties and has been used in the past to preserve some foods, such as fish and meat. This can help extend the shelf life of products.
Beverage Production: In some regions, ammonium chloride is used as an ingredient in traditional beverages, providing a unique flavor profile. For example, it has been used in some Scandinavian spirits and herbal liqueurs.
pH Control: In some food processing applications, ammonium chloride can be used to control the pH of certain products or processes. It can act as a pH regulator and adjust acidity levels.
Agriculture:
Fertilizer Additive: Ammonium chloride can be used as a nitrogen source in fertilizer mixtures. While it provides a source of nitrogen for plants, its use is less common than other nitrogenous fertilizers due to factors such as potential soil acidification and chloride ion accumulation that can harm some plants. It is used cautiously and often in combination with other fertilizers to reduce adverse effects.
Soil Amendment for Salt-Affected Soils: In areas with salt-affected or saline soils, ammonium chloride can be used as a soil conditioner. It can help reduce the concentration of sodium ions in the soil and improve soil structure and permeability. However, it should be used with caution and soil testing is essential to determine appropriate application rates.
Ammonium Chloride as a Herbicide: In some cases, ammonium chloride has been used as a non-selective herbicide. When applied to plant leaves, it can dry out and kill plants. However, its use as a herbicide is less common today and safer and more effective herbicides are available.
Feed Industry:
Animal Feed Additive: In animal nutrition, ammonium chloride can be added to animal feeds as an additional source of chloride and as an acidifier to help control urine pH in some animal species, particularly poultry and pigs. It may help prevent urinary stone formation in animals.
Aquaculture: In fish farming (aquaculture), ammonium chloride can be used as an additional source of ammonia in water to stimulate the growth of beneficial nitrifying bacteria that convert ammonia to nitrate. This can help maintain water quality in aquaculture systems.
Metal Industry:
Metal Surface Preparation: Ammonium chloride is used as flux in metal processing processes such as soldering and brazing. It helps clean metal surfaces by removing oxide layers and other foreign substances, and ensures better adhesion of solder or brazing materials to the metal.
Galvanizing: In the galvanizing process, ammonium chloride is used to flush and clean steel surfaces before coating them with a layer of zinc. This provides a smooth and uniform zinc coating that protects the steel from corrosion.
Electroplating: In some electroplating processes, ammonium chloride can be used as an additive to electrolyte solutions to improve the coating quality and control the deposition rate.
Textile Industry:
Fixing Agent: Ammonium chloride is used as a fixing agent in textile dyeing. It helps fix or fix dyes onto textile fibers, ensuring that the color remains durable and fade-resistant during subsequent washing and exposure to light.
Mordant: In some dyeing processes, ammonium chloride can act as a mordant. Mordant is a substance that helps dyes bind to textile fibers more effectively. It can improve the color fastness of dyed fabric.
Resist Printing: Ammonium chloride is sometimes used in resist printing techniques. Resist printing involves applying a substance that resists dye penetration to specific areas of the fabric, creating a pattern or design. Ammonium chloride can be used as part of the resistant paste.
Batik Dyeing: In batik dyeing, a traditional Indonesian technique, wax is applied to the fabric to create a pattern and then the fabric is dyed. Ammonium chloride can be used in dye baths to increase dye penetration and adhesion to wax-free areas of the fabric.
Wool Dyeing: Ammonium chloride can be used to dye wool and other animal-based fibers. It helps increase the affinity of the dye to the fibers and increases color fastness.
Printing Pastes: In textile printing, ammonium chloride can be used in the preparation of printing pastes and thickeners. These pastes are applied to the fabric in specific patterns before dyeing or printing.
pH Control: Ammonium chloride can act as a pH regulator in various dyeing and textile processes. It is very important to control the pH of the dye bath to achieve consistent and desired color results.
Cleaning and Degreasing: In some cases, especially in wool processing, ammonium chloride can be used to clean and degrease textile fibers.
Dye Bath Additive: Can be added to dye baths to improve the overall dyeing process and the quality of dyed textiles.
Leather Industry:
Descaling and Stracking Process: Ammonium chloride is used in the descaling and stripping stages of leather processing. Descaling is the process of removing excess lime from hides or skins that were initially treated with calcium hydroxide (lime) during the dehairing process. Ammonium chloride helps neutralize excess lime and prepares the leather for further treatments. Stroking is the next step that softens and smoothes the leather.
pH Regulation: Ammonium chloride can act as a pH regulator in leather processing. It is very important to maintain the correct pH level to control the chemical reactions that occur during tanning and other leather processing processes.
Tanning: Ammonium chloride can be used as an auxiliary tanning agent in some leather tanning processes, but chromium is less commonly used for this purpose compared to other tanning agents such as vegetable extracts or aldehydes. Its use can help improve leather properties such as tensile strength and water resistance.
Cleaning and Degreasing: Ammonium chloride can be used as part of the cleaning or degreasing process to remove impurities and excess oil from animal hides and skins prior to tanning.
Enzyme Activation: In some enzymatic leather processing methods, ammonium chloride can be used to activate enzymes that help break down proteins and fats in the hide or leather.
Removal of Residual Lime: After descaling, ammonium chloride can be used to ensure complete removal of residual lime, which is necessary to prevent undesirable reactions in later stages of leather processing.
Cooling/Heating:
Laboratory Cooling Baths: In laboratory settings, ammonium chloride is commonly used to cool reaction vessels or samples in cooling baths. The cooling bath consists of a container filled with a mixture of ammonium chloride and water or other suitable solvents. When an object or sample is placed in the bath, dissolving ammonium chloride in water absorbs heat from the object, thereby cooling it. This is especially useful for controlling reaction temperatures in chemistry experiments.
Cooling Systems: Ammonium chloride was used as a coolant in old cooling systems. It can be used in absorption cooling systems where it absorbs ammonia gas (NH3) to create a cooling effect. However, this practice is less common today, as modern cooling systems generally use more efficient and environmentally friendly refrigerants.
Cooling of Electronic Components: In some applications, ammonium chloride can be used to cool electronic components. It is often found in specific cooling pads or solutions designed to dissipate heat from electronic devices such as laptops or gaming consoles.
Heat Removal in Industrial Processes: Ammonium chloride-based cooling baths can be used in some industrial processes where local cooling is required. This can help prevent overheating and maintain the desired operating temperature of machinery and equipment.
Thermal Energy Storage: Ammonium chloride can be used in thermal energy storage systems. It absorbs heat when dissolved and releases heat when crystallized. This feature can be used for energy storage and recovery in certain applications.
Photography:
Developer Solutions: Ammonium chloride has been used in developer solutions for black and white photography. Developers are chemicals that reduce exposed silver halide crystals in photographic emulsions to create visible images. Ammonium chloride was sometimes used as an accelerator or limiter to control the development process.
Fixing Baths: Ammonium chloride has been used in fixing baths in some photographic processes. Fixatives are chemicals that remove unexposed and unprocessed silver halide crystals from photographic prints or films, leaving behind the enhanced image. Ammonium chloride was used to help dissolve and remove any exposed silver halide crystals.
Emulsion Preparation: Ammonium chloride can be used in the preparation of photographic emulsions, which are photosensitive coatings applied to photographic plates, papers, or films. It may have been added to adjust the sensitivity of the emulsion or change its properties.
Toning: Some toning processes in black and white photography used ammonium chloride to change the colors of photographic prints. Toning can change color or increase the stability of the final print.
Alternative Processes: Some alternative or historical photographic processes, such as gum bichromate printing or salt paper printing, may involve the use of ammonium chloride as an ingredient in sensitizing or developing solutions.
Fire Extinguishing Devices:
Dry Powder Fire Extinguishers: Some types of dry powder fire extinguishers use ammonium chloride as the primary extinguishing agent. Known as "salt cake" or "chemical foam" extinguishers, these extinguishers contain a mixture of ammonium chloride and other chemicals. When ammonium chloride is discharged onto a fire, it releases ammonia gas, which suppresses flames by diluting the oxygen around the fire. The foam-like consistency of the discharged material also helps extinguish the fire and cool surfaces.
