Methods of production

By dicyandiamide in methanol solvent, at 200℃ and ammonia reaction. This method consumes 1180kg dicyandiamide (98%) and 30kg liquid ammonia per ton of product. Compared with this method, urea method has low cost and is widely used at present. Urea with ammonia as the carrier, silica gel as the catalyst, boiling reaction at 380-400 chemical book temperature, decomposition to generate cyanic acid, and further condensation to produce melamine. After cooling and trapping, the crude product is obtained, and then dissolved, impurities are removed, and the finished product is recrystallized. The urea process consumes about 3800kg of urea and 500kg of liquid ammonia per ton of product to produce melamine.

Details:

White monoclinic crystal. A little soluble in water, ethylene glycol, glycerin and pyridine. Slightly soluble in ethanol, insoluble in ether, benzene, carbon tetrachloride.

Industrial additive, widely used in plastics, paint textile, paper making. Recently detected items: milk powder, feed enterprises add melamine to increase protein content. Simply adding a few nitrogen-rich chemicals to the Chemicalbook test can give the impression that protein levels are up to standard. Therefore, melamine is also known as "protein essence ". In large quantities, it can damage the reproductive and urinary systems of humans and animals, produce kidney and bladder stones, and result in renal failure and death.
