Trichloroisocyanuric acid water chemical

Trichloroisocyanuric acid (TCCA), also known as trichloro-s-triazinetrione or by its CAS number 87-90-1, is a strong oxidizing and chlorinating agent. Here are some key points about TCCA:
Chemical Properties: TCCA is a white crystalline powder with a pungent odor. It has a high content of available chlorine, typically around 90%, which makes it an effective disinfectant and bleaching agent

Disinfection and Bleaching: It is widely used for disinfection in various applications, including water treatment, swimming pools, and industrial processes. TCCA is effective against a broad spectrum of microorganisms, including bacteria, viruses, fungi, and spores

Industrial Applications: In the textile industry, TCCA is used as a bleaching agent for cotton, linen, wool, synthetic fibers, and blends. It is also used in the food industry as a disinfectant, replacing chloramines, and as a decolorizing and deodorizing agent for starch

Safety and Toxicity: Trichloroisocyanuric Acid is classified as a strong oxidizer and can be hazardous. It is important to handle it with care to avoid skin and eye contact, and to prevent inhalation of dust

Environmental Considerations: TCCA is biodegradable and breaks down into triazinetrione, which is non-toxic and has various uses, such as in the production of resins, paints, adhesives, and plastics

Synthesis: TCCA is synthesized through the chlorination of cyanuric acid, which is obtained from the thermal decomposition of urea

Physical Properties: It has a melting point of around 249-251°C and is soluble in water, with a solubility of approximately 1.2 g per 100 mL at 25°C
