Properties and stability
Avoid contact with moist air. Avoid contact with strong oxidants, strong acids, water, and alcohols.
Storage method
Stored in a cool, dry and well-ventilated warehouse. Keep away from fire and heat sources. Keep container tightly sealed. They should be stored separately from oxidants, acids, alcohols, and food chemicals, and avoid mixed storage. Equipped with the appropriate variety and quantity of fire equipment. Suitable materials should be available in the storage area to contain spills.
Synthesis method
The production of cyanuric chloride usually consists of two processes: cyanogen chloride preparation and cyanogen chloride polymerization. There are many methods to generate cyanogen chloride, such as the synthesis method of methyl thiocyanate and chlorine, the synthesis method of dissolving hydrocyanic acid in chloroform and passing chlorine gas, the hydrocyanic acid method, the sodium cyanide method, the urea method, and the hydrocyanic acid method. The current industrial production of cyanuric chloride generally uses two methods: sodium cyanide and hydrocyanic acid as raw materials. 1. Sodium cyanide method: Use sodium cyanide as raw material to react with chlorine to form cyanogen chloride, which is then polymerized to form cyanuric chloride, which is then quenched and crystallized to obtain the product. Raw material consumption quota: sodium cyanide 1073kg/t, chlorine 1700kg/t. 2. The hydrocyanic acid method uses hydrocyanic acid as raw material and reacts with chlorine to form cyanogen chloride, which is then polymerized to form cyanuric chloride, which is then quenched and crystallized to obtain the product. Raw material consumption quota: hydrocyanic acid 500kg/t, chlorine 1200kg/t.
Purpose
Cyanogen chloride is an important intermediate for the production of highly efficient and low-toxic triazepine herbicides and insecticides. It is also an intermediate for the production of fluorescent whitening agents, reactive dyes for dyeing polyester and other synthetic fibers. body. It is also used in the production of synthetic resins, rubber, polymer antioxidants, explosives, fabric anti-shrink agents, surfactants, etc.
Mainly used to prepare reactive dyes, direct dyes, metal complex dyes, acid dyes, vat dyes or disperse dyes, etc. Such as direct lightfast yellow L-5R, reactive bright yellow X-6G, reactive bright yellow X-7G and other dyes.
