The production method of melamine cyanide plant

The production of melamine is usually made up of chloroform and chloride polymerization. Generated cypermethrin there are many methods, such as the synthesis of methyl thiocyanate and chlorine, hydrocyanic acid soluble in chloroform bubbled into chlorine synthesis, hydrocyanic acid, sodium cyanide, urea, chlorine hydrocyanic acid and chlorine direct cyanidation etc., the current industrial production 3 get together cyanogen chloride with sodium cyanide and hydrocyanic acid as raw material of two kinds of methods. 1. Sodium cyanide method was used to generate the chlorine cyanide with sodium cyanide, and then polymerized to produce the product of the cold and crystallization. Raw material consumption quota: sodium cyanide 1073kg/t, chlorine gas 1700kg/t. 2. Hydrocyanic acid method was used to produce the cyanogen with hydrocyanic acid as raw material and chlorine gas, and then polymerized to produce melamine, which was then cooled and crystallized to produce the product. Raw material consumption quota: 500kg/t and 1200kg/t of hydrogen cyanide.
