Trichloroisocyanuric acid manufacturing process

Product Description:
Trichloroisocyanuric acid is a commonly used swimming pool disinfectant, and its manufacturing process is not complicated. So today we will talk about the manufacturing principle of Trichloroisocyanuric acid.

Trichloroisocyanuric acid specification

Here are some of the typical specifications for Trichloroisocyanuric acid (TCCA):

Chemical formula: C3Cl3N3O3

Molecular weight: 232.41 g/mol

Appearance: White crystalline powder or granules

Melting point: 247-251°C

Solubility: Soluble in water (slightly soluble in organic solvents)

pH value (1% solution): 2.7-3.3

Available chlorine: 90% min or 98% min

Moisture content: 0.5% max or 0.3% max

Granularity: 8-30 mesh, 20-60 mesh, or as per customer requirements


The available chlorine content is one of the most important specifications for TCCA, as it indicates the amount of chlorine available for disinfection purposes. TCCA with a higher available chlorine content is generally more effective in killing bacteria and viruses.

The moisture content is another important specification, as it can affect the stability and shelf life of TCCA. Higher moisture content can lead to decomposition and reduced efficacy.

The granularity of TCCA can also vary depending on the application, with smaller granules typically used in water treatment and larger granules used in swimming pool disinfection.

It is important to note that different manufacturers may have slightly different specifications for TCCA, so it is important to refer to the specific product data sheet for detailed information.

Main uses of Trichloroisocyanuric acid

Trichloroisocyanuric acid (TCCA) is a chemical compound that is commonly used as a disinfectant, sanitizer, and bleaching agent in various settings. Here are some of the main uses of TCCA:


Swimming pools: TCCA is commonly used to sanitize and disinfect swimming pools, hot tubs, and spas. It is highly effective in killing bacteria, viruses, and other harmful microorganisms that can cause infections.

Water treatment: TCCA is used in water treatment facilities to disinfect drinking water and wastewater. It can help to remove impurities and kill harmful bacteria and viruses, making the water safe for human consumption and other uses.

Food and beverage industry: TCCA is used as a sanitizer and disinfectant in the food and beverage industry to prevent the growth of harmful bacteria and viruses that can contaminate food products.

Agriculture: TCCA is used in agriculture as a disinfectant and fungicide to control the growth of harmful microorganisms on crops and in soil.

Household cleaning: TCCA is used in household cleaning products, such as bleach and disinfectant sprays, to kill germs and bacteria on surfaces.

Industrial applications: TCCA is used in various industrial applications, such as textile manufacturing, pulp and paper processing, and oil drilling, as a bleaching agent and disinfectant.

Overall, TCCA is a versatile and effective chemical that has a wide range of uses in different industries and settings. However, it is important to handle and use TCCA safely and carefully, as it can be hazardous if not used properly.

Trichloroisocyanuric acid manufacturing process

Trichloroisocyanuric acid (TCCA) is a commonly used chlorine-based disinfectant and bleaching agent. The manufacturing process of TCCA involves the following steps:

Chlorination: The starting material for TCCA manufacturing is cyanuric acid. Chlorine gas is passed through a mixture of cyanuric acid and hydrochloric acid at a temperature of about 80-90°C. The reaction produces dichloroisocyanuric acid (DCCA).

3H3C3N3O3 + 3Cl2 + 6HCl → 3(C3N3O3Cl2) + 6H2O

Dichlorination: The DCCA produced in the previous step is then further chlorinated with chlorine gas at a temperature of about 80-90°C to produce TCCA.


(C3N3O3Cl2) + Cl2 → C3N3O3Cl3 + HCl


Neutralization: The TCCA is then neutralized with an alkaline substance such as sodium carbonate or sodium hydroxide to remove excess acid and to adjust the pH of the final product to around 7.


C3N3O3Cl3 + Na2CO3 → C3N3O3(NaCl) + CO2 + H2O


Drying: The resulting TCCA is then dried and packaged for distribution.


It is important to note that the manufacturing process of TCCA requires careful handling of chlorine gas and hydrochloric acid, which are hazardous materials. Proper safety measures and equipment must be used to ensure the safety of the workers and the environment.

Trichloroisocyanuric acid packaging

Trichloroisocyanuric acid (TCCA) is typically packaged in a variety of forms, depending on the intended use and application. Here are some common packaging options for TCCA:

Plastic drums: TCCA is often packaged in plastic drums with airtight lids to prevent moisture and exposure to air, which can cause degradation of the product. The drums can range in size from 25kg to 50kg.

Fiber drums: TCCA can also be packaged in fiber drums, which are made from a combination of paper and plastic materials. Fiber drums are lighter and more environmentally friendly than plastic drums, but may not be as airtight.

Bags: TCCA can be packaged in bags made of various materials, such as plastic or woven polypropylene. The bags can range in size from small 1kg bags to large 1000kg bags, depending on the application.

Tablets: TCCA is also available in tablet form, which can be packaged in plastic jars or tubs. The tablets can range in size from small 20g tablets to large 200g tablets.

Regardless of the packaging form, it is important to store TCCA in a cool, dry place away from sunlight and heat sources. TCCA should also be kept away from combustible materials and incompatible chemicals. Always refer to the manufacturer's guidelines and safety data sheet for specific storage and handling instructions.
