What is Cyanuric chloride?

With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Cyanuric chloride which has developed particularly rapidly in recent years. Do you know about Cyanuric chloride?


The official answer: Melamine is an organic compound with the molecular formula C3Cl3N3, which is an important fine chemical product with a wide range of uses. It is an intermediate in the pesticide industry, a raw material for the manufacture of reactive dyes, a variety of auxiliaries for the production of organic industries, such as fluorescent whitening agents, anti-shrinking agents for textiles, surfactants, etc. It is one of the raw materials for rubber accelerators and national defense for the manufacture of explosives, as well as a raw material for the pharmaceutical and pesticide It is also used as raw material for the synthesis of drugs in the pharmaceutical and pesticide industry.

What’s the application of Cyanuric chloride?

Melamine, also known as cyanuric chloride, is a white crystal with strong irritating chlorine odor, corrosive to skin, irritating to eyes and lacrimogenic. Melting point 145℃, boiling point 190℃, UVλmax 241nm (ethanol). Soluble in anhydrous ethanol, ethyl ether, chloroform, acetic acid and acrylonitrile, insoluble in cold water. The action of melamine with water is slow when cooled and hydrolyzed quickly to cyanuric acid (C3H3O3N3) and hydrochloric acid when heated, and the products are relatively soluble in water, so they can be separated using extraction methods. It is partially converted to cyanuric acid by the action of concentrated nitric acid and concentrated sulfuric acid at room temperature, and triglycerides of orthocyanuric acid by the action of sodium alcohol, which can also act with ammonia, amine and phenol. Preparation: It is obtained by reacting anhydrous hydrocyanic acid with dry chlorine gas in daylight (or in anhydrous ether), or by heating cyanuric acid with excess phosphorus pentachloride. Uses: Cyanuric acid is an important intermediate for the production of high-efficiency and low-toxicity homotriazole herbicides and insecticides, as well as an intermediate for the production of reactive dyes, and can be used as a raw material for synthetic resins, rubber, polymer antioxidants, cyanal resins, photographic sensitizers, fluorescent whitening agents, adhesives, and a variety of pharmaceutical drugs. In recent years, the consumption of cyanuric chloride in China has been growing rapidly, with an average annual growth rate of 32.2% from 1998 to 2004, and the demand for cyanuric chloride reached 50,000 tons in 2005. Since there are many subsequent products of melamine and the market demand is large, related enterprises and research institutions in various countries have been developing downstream products and applications of melamine. As a result, new products derived from melamine are emerging and the market demand will be further expanded. The related chemical reaction in which melamine is involved: from 2-amino-4-nitrophenol diazotization, coupled with H acid, treated with chromium and cobalt complex, condensed with melamine first, then condensed with ammonia to obtain reactive black K-BR. mainly used for printing on cotton and polyester/cotton fabric. Using melamine as raw material, it reacts with ethylamine in trichloroethylene solution at 20-30℃ to produce 2,4-dichloro-6-ethylamino-1,3,5-triazine, and then reacts with ammonia to produce 2-amino-4-chloro-6-ethylamino-triazine, and then reacts with 2-chloro-2-methylpropionitrile to produce selective herbicide gramoxone, which is used in corn field to prevent and control annual or perennial narrow-leaved or broad-leaved It is used to control annual or perennial narrow- or broad-leaved weeds in corn fields. It is used in the synthesis of fluorescent whitening agents, reactive dyes, pharmaceuticals, pesticides, etc. Melamine is an important intermediate for the production of high-efficiency and low-toxicity homotriazobenzene herbicides and insecticides, as well as an intermediate for the production of fluorescent whitening agents and reactive dyes for dyeing Chemicalbook colors of polyester and other synthetic fibers. It is also used in the production of synthetic resins, rubber, polymer antioxidants, explosives, fabric anti-shrinkage agents, surfactants, etc. Melamine is an important fine chemical product with a wide range of uses, it is an intermediate in the pesticide industry, is the raw material for the manufacture of reactive dyes, can be used as a variety of additives in the production of organic industry, Chemicalbook such as fluorescent whitening agent, textile anti-shrinking agent, surfactants, etc., is a rubber accelerator and one of the raw materials used in the manufacture of explosives for national defense, but also the pharmaceutical and pesticide industry for the synthesis of drugs It is also used as a raw material for the synthesis of drugs in the pharmaceutical and pesticide industry.

Peter has been my partner for many years, we met at the Shanghai CPHI Fair in 2014, for the first time I didn't have much interest in Peter's products because our company had a stable supplier. Although we didn't work together, Peter would often send me important news and interesting trend information about the industry, so we became good friends, even though I didn't place any orders with him during this time, even if it was a sample order. In September 2016, our original supplier was unable to provide us with the quality and delivery guarantees we needed, so I first thought of Peter and his company. Until now, we have maintained a very good personal friendship in addition to a steady business relationship.

In all my years of sourcing from China, I first time to found that working with Sincere Chemical was so good, they helped me with all the production and delivery as well as a lot of technical expertise, which saved me a lot of time. When I first approached Peter for a quotation for Optical Brightener, he made me a detailed quotation with not only prices but also foreign trade details, company profile, company strengths, R&D capabilities, production capacity, packaging methods, raw material control, environmental protection, and much more. This information was a very important reference for me in making purchasing decisions. Sincere Chemical is a trustworthy supplier and I believe our business will grow from strength to strength!

Hi, I'm Kim, I'm Peter's partner and although I don't like him very much (because he never gives me more money for my prices, hahaha) I'm still willing to write him customer feedback. As an international buyer, I have to deal with a lot of things every day and my inbox is often full of development letters. It's a lot of junk and meaningless pleasantries, which I don't like that much, but Peter's emails always give me a better understanding of the product and the industry. I am also very pleased with his work ethic, and I am very happy with his work every time I work with him, not only in providing quotations but also in facilitating all the details of my work so that I can concentrate more on other things, so he is the best supplier for me. Although his prices are not the lowest among all suppliers, his products give me the greatest peace of mind.
