    Items Specifications
    Stroma 50%AlcoholWater
    Form Liquid
    Storage conditions 2-8℃ storage and Avoided from light. Equilibrating in room temperature (20±3℃) before use, and shaken well to ensure uniformity. Once ampoules opened, it cannot be used as reference material after being melted again. Preventing contamination during use.
    Applications This reference material is mainly used for the determination of melamine in raw milk and dairy products
    Matters needing attention Before use, it should be kept constant temperature to (20±3)℃, and shake well. Once the ampoules are opened for one-time use, they should be strictly prevented from contamination during use.
    Reference material 2015 2020 Chinese Pharmacopoeia fourth edition
    Physical and chemical properties Properties: White monoclinic prism. Melting point 347 ℃, relative density 1.537(16/4 ℃). Slightly soluble in water, hot ethanol, glycerin and pyridine, insoluble in ether, benzene and Carbon tetrachloride. Heating sublimates, sharp heating decomposes. Preparation method: Dicyandiamide is obtained by reacting with ammonia at 200 ℃ in methanol solvent. This method consumes 1180kg of dicyandiamide (98%) and 30kg of liquid ammonia per ton of products. 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, in 380-400 ℃ temperature boiling reaction, first decomposition to generate cyanic acid, and further condensation to generate melamine. The generated trimeric amine gas is cooled and trapped to obtain a crude product, which is then dissolved to remove impurities and recrystallize to obtain a finished product. The production of melamine by urea method consumes about 3800kg of urea and 500kg of liquid ammonia per ton of products. Uses: Melamine resin can be prepared by condensation polymerization with formaldehyde, which can be used in plastic and coating industry, and can also be used as anti-folding and anti-shrinkage treatment agent for textile products. Its modified resin can be used as metal coating with bright color, durability and good hardness. It can also be used for strong and heat-resistant decorative sheet, moisture-proof paper and gray leather tanning agent, adhesive for synthetic fireproof laminate, fixing agent or hardener of waterproof agent, etc. 582 melamine resin prepared from melamine, formaldehyde and butanol. Used as a leveling agent for solvent-based polyurethane coatings with excellent effect.
