Storage method

This product should be sealed and stored in a cool, ventilated warehouse, away from fire and heat sources.

Synthesis method

It is synthesized using benzonitrile and dicyandiamide as raw materials. The synthesis reaction is carried out in an organic solvent (butanol), using sodium hydroxide as a catalyst. The reaction releases heat and precipitates benzene melamine. The finished product is obtained by vacuum filtration, water washing and drying. The industrial product is white powder with a melting point of 224-228°C. Each ton of product consumes 580kg of benzonitrile and 580kg of dicyandiamide.


Manufacture of thermosetting resins, pesticides, pharmaceuticals and dyes. ​​Used to produce thermosetting resins, modified resins, amino coatings and plastics, medicines, pesticides and dyes. 1. Benzene melamine for metal coatings is the same as melamine. In addition to being used as an intermediate for special chemicals, most of them react with formaldehyde to form hydroxymethylated benzene melamine, which is used as a molding material. Resin fiber processing aid for lamination. The hydroxymethylated benzoguanamine is further denatured with alcohol to obtain an alkylate, which becomes a coating mainly used for metals. 2. Decorative board: Using benzene melamine as decorative board is one of the most distinctive ways of using it. In addition, resin-impregnated paper is used as a veneer for concrete slabs, which can make the surface of the concrete slab smooth and flat, facilitate demoulding, and have excellent durability. Fluorescent pigments based on benzene melamine resin are used as colorants and printing inks for polypropylene, polyethylene, hard and soft polyvinyl chloride and other resins, and their uses and demand are also developing. Benzinated melamine is further reacted to produce butanol etherified benzinated melamine formaldehyde resin, and methanol etherified benzinated melamine formaldehyde resin. They can be used as cross-linking agents in baking coatings and can be mixed with alkyd resins, acrylic resins, etc. to make coatings. In addition, the methylol compound of benzomelamine can be mixed with urea-formaldehyde resin, phenolic resin, and melamine-formaldehyde resin to make molding materials. It is used to manufacture modified melamine formaldehyde resin, which improves its solubility in organic solvents after modification.
