Storage method
1. This product should be sealed with argon gas and stored in a dry place below 0℃ and protected from light.
2.During storage and transportation, prevent moisture, sunlight, and contact with acids, alkalis, and easily oxidized organic matter to avoid decomposition, failure, and explosion.
Synthesis method
1. Using urea and ammonium chloride as the main raw materials, cyanuric acid is produced through thermal cracking , and then prepared by chlorination. The production process of trichloroisocyanuric acid includes solid phase method and liquid phase method. The solid-phase method has backward technology, high cost, harsh environmental conditions, difficult by-products to handle, and small production scale. The liquid phase production process is to react in high-boiling solvents such as sulfolane and dimethylformamide. The product gradually precipitates as the reaction proceeds. The product is cooled and separated, and the solvent is regenerated and recycled. This method can produce continuously, has high yield and no waste water discharge. However, this method has complex process and high investment. There are two main chlorination methods: one is the alkaline earth metal method, Ca(OH)2 aqueous solution and cyanuric acid aqueous solution are mixed, chlorine reacts, and the reactants are cooled, filtered, washed, and dried to obtain the product; the other is Hypochlorous acid method, hypochlorous acid aqueous solution and cyanuric acid slurry react at low temperature, precipitate, filter, wash and dry to obtain the product.
Isocyanuric acid is dissolved in sodium hydroxide solution, and then chlorine gas is slowly introduced at low temperature to perform a chlorination reaction, and trichloroisocyanuric acid is precipitated. After filtration, washing and drying, the product is obtained. The reaction formula is as follows:
Purpose
1. Biochemical research. Substrate for measuring porphobilinogen dehydrogenase activity. 2.This product has extremely strong sterilizing and bleaching effects. It is widely used in civil sanitation, animal husbandry and plant protection as an efficient sterilizing and disinfecting agent for cotton and linen chemical fiber fabrics. Washing bleach, wool anti-shrinkage agent, can also be used in rubber chlorination, battery materials, organic synthesis industry and dry bleaching of clothing. The bactericidal effect of trichloroisocyanuric acid is similar to that of hypocyanurate and chlorine, and it is an oxidizing bactericide. It can replace liquid chlorine hypochlorite in circulating cooling water systems. Mainly used for disinfection and sterilization of drinking water, industrial circulating water, swimming pools, restaurants, hotels, public places, homes, hospitals, poultry eggs and the prevention and treatment of fish lesions. It has a killing effect on almost all fungi, bacteria, and virus spores, and is safe and convenient to use. This product can also be widely used in food, dairy products, rice seed treatment, fruit preservation, fiber bleaching, wool shrinkage prevention, daily chemical decolorization, wood mildew prevention and papermaking, rubber oxidation and battery materials. TCCA has excellent bactericidal performance and is a new generation of broad-spectrum, efficient, low-toxic bactericide, bleach and anti-shrink agent.
