Cyanuric Acid (chemical formula: C₃H₃N₃O₃) is a heterocyclic compound that consists of a triazine ring (a six-membered ring with alternating nitrogen and carbon atoms) with three carboxylic acid groups (-COOH) attached. It is a white crystalline solid that is relatively insoluble in water and has a mild, weakly acidic nature.
Proprietà chiave:
- Aspetto: Cyanuric acid is a white crystalline powder or solid.
- Punto di fusione: It has a high melting point of around 330°C (626°F).
- Solubilità: Cyanuric acid has low solubility in water, but it dissolves in strong bases and in hot water.
- Odor: It is odorless.
- Stability: Cyanuric acid is stable under normal conditions but may degrade under high temperatures or in the presence of strong acids or bases.
Uso comune:
- Swimming Pools: One of the most common uses of cyanuric acid is as a stabilizer for chlorine in swimming pools. It helps prevent the degradation of chlorine by ultraviolet (UV) light, thus extending the effectiveness of chlorine as a disinfectant. Cyanuric acid binds with chlorine to form a stable compound, which gradually releases chlorine to maintain a safe water quality.
- Herbicide Production: Cyanuric acid is used as a precursor in the production of some herbicides e pesticidi, particularly those in the triazine class, such as atrazine. These compounds are widely used in agriculture for weed control.
- Industrial and Chemical Manufacturing: It is used in the synthesis of other chemicals, including biocides, plastica, e resins. Cyanuric acid is also used in the production of melamine, a chemical important in making plastics and adhesives.
- Melamine Resin: Cyanuric acid is a precursor in the manufacture of melamine resin, a durable plastic used in products such as laminates, rivestimenti, and kitchenware.
- Water Treatment: In alcuni casi, L'acido cianurico viene utilizzato come un scavenger per ioni metallici e può aiutare a mantenere la qualità dell'acqua in torri di raffreddamento e trattamento dell'acqua industriale sistemi.
Considerazioni sulla sicurezza e sull'ambiente:
- Rischi per la salute: L'acido cianurico stesso è relativamente basso in tossicità; Tuttavia, quando viene utilizzato in piscine o altri sistemi idrici, gestione impropria o uso eccessivo può causare problemi. Alti livelli di acido cianurico nell'acqua della piscina possono causare blocco del cloro, dove il cloro non è efficace nella disinfezione, che porta alla potenziale crescita di alghe e batteri.
inalazione o ingestione di acido cianurico in quantità significative può causare irritazione alle vie respiratorie, pelle, e gli occhi, ma la tossicità acuta è generalmente bassa.
- impatto ambientale: L'acido cianurico può persistere nell'ambiente, specialmente nei sistemi idrici. Alti livelli di acido cianurico nell'acqua della piscina possono influenzare il aquatic life if discharged into rivers or lakes. It is recommended that cyanuric acid be managed and disposed of properly to minimize its environmental impact.
CAS Number: 108-80-5
The CAS number for cyanuric acid is 108-80-5, which is used for its identification in scientific, regulatory, and industrial contexts.
Conclusion:
Cyanuric acid is a versatile chemical, most notably used as a chlorine stabilizer in swimming pools and a precursor in the production of agricultural chemicals and plastics. While it is relatively low in toxicity, it requires careful management, particularly in water systems, to ensure safety and environmental protection.
