Product Description
Basic Information
- Product Name:Ammonium Carbonate Introduction
- Chemical Formula: (NH4)2CO3
- Molecular Weight: Approximately 96.09 g/mol
- CAS Number: 506-87-6
- Appearance: Presents as a white crystalline powder. It has a characteristic pungent odor of ammonia due to its tendency to decompose and release ammonia gas.
Physical Properties
- Density: Around 1.5 g/cm³.
- Melting Point: Decomposes rather than melting at a relatively low temperature, typically around 58°C. The decomposition reaction is as follows: (NH4)2CO3Δ2NH3↑+CO2↑+H2O.
- Solubility: Soluble in water. At 20°C, it can dissolve to some extent in water to form an aqueous
- solution, but is insoluble in most organic solvents like ethanol and acetone.
Chemical Properties
- Thermal Instability: As mentioned above, ammonium carbonate is thermally unstable. When heated, it readily breaks down into ammonia, carbon dioxide, and water. This property makes it useful in applications where controlled release of these gases is required.
- Acid - Base Reaction: It reacts with acids. For example, when reacting with hydrochloric acid (HCl), the chemical equation is (NH4)2CO3+2HCl=2NH4Cl+CO2↑+H2O. This reaction releases carbon dioxide gas, which can be utilized in certain industrial processes or laboratory experiments.
- Aqueous Solution Chemistry: In water, the ammonium ions (NH4+) can undergo hydrolysis to a certain extent, making the solution slightly acidic. The hydrolysis reaction is NH4++H2O⇌NH3⋅H2O+H+, while the carbonate ions (CO32−) can also react with water, contributing to the complex acid - base balance of the solution.
Applications
- Food Industry
- Leavening Agent: Historically, it was used as a leavening agent in baking. When heated during the baking process, it decomposes to release carbon dioxide, which causes the dough to rise and gives the baked goods a lighter texture. Although it has been largely replaced by baking powder and baking soda in modern times, it is still used in some traditional recipes, especially in certain types of cookies and crackers.
- Flavor Adjustment: In some confectionery products, it can be used to adjust the flavor slightly, adding a unique taste element due to the presence of ammonia.
- Pharmaceutical Industry
- Excipient: It can serve as an excipient in pharmaceutical formulations. For example, in tablet manufacturing, it may be used to help with the disintegration of the tablet in the body or to adjust the pH of the formulation.
- Reagent in Synthesis: In some pharmaceutical synthesis processes, ammonium carbonate can act as a source of ammonia or carbonate ions, participating in chemical reactions to produce active pharmaceutical ingredients or intermediates.
- Chemical and Industrial Applications
- Precursor for Ammonium Salts: It is an important precursor for the synthesis of other ammonium salts. For instance, it can be used to produce ammonium bicarbonate, ammonium carbamate, etc., which have wide applications in the chemical industry, such as in the production of fertilizers, plastics, and fibers.
- Laboratory Reagent: In laboratories, it is used as a reagent for various chemical reactions, including pH adjustment, precipitation reactions (such as precipitating metal ions as carbonates), and as a source of ammonia and carbon dioxide gases for experiments.
- Textile and Leather Industry: In the textile industry, it can be used in dyeing processes to adjust the pH of the dye bath, which helps in better color absorption and fixation. In the leather industry, it can be used to neutralize acidic substances during the tanning process.
Safety and Handling
- Toxicity: Ammonium carbonate is harmful if ingested, inhaled, or comes into contact with the skin or eyes. Inhalation of its dust or the ammonia gas it releases can irritate the respiratory tract, causing symptoms such as coughing, wheezing, and shortness of breath. Prolonged exposure may lead to more serious respiratory problems. Ingestion can cause irritation to the gastrointestinal tract, resulting in nausea, vomiting, and abdominal pain. Skin and eye contact can cause irritation, redness, and in severe cases, damage to the eyes.
- Safety Precautions: When handling ammonium carbonate, it is necessary to wear appropriate personal protective equipment, including gloves, safety goggles, and a dust - mask or respirator. It should be stored in a cool, dry, well - ventilated area, away from sources of heat, ignition, and incompatible substances such as acids. In case of a spill, the area should be evacuated, and the spill should be cleaned up carefully following proper safety procedures.
Environmental Impact
- Degradation: In the environment, ammonium carbonate can decompose into ammonia, carbon dioxide, and water. Ammonia can contribute to the eutrophication of water bodies if it enters aquatic ecosystems in large amounts, potentially disrupting the balance of the ecosystem. However, carbon dioxide and water are relatively harmless components of the natural environment.
- Disposal: When disposing of ammonium carbonate waste, it should be done in accordance with local environmental regulations. In some cases, it may need to be treated to neutralize the ammonia content before disposal to minimize its impact on the environment.
