Propylene Tungsten Trioxide Preparing Tungsten Carbide Powder

Propylene is colorless. It is slightly narcotic, flammable. It dissolves in water; and not dissolves in organic solvents. It is low toxicity substance. Propylene is the base stock material of three syntheses, mainly for the production of polypropylene, acrylonitrile, isopropanol, acetone, and propylene oxide. In addition, propylene is reacted on olefin bond; it can also react in the methyl group. Propylene polymerization in the presence of an acidic catalyst can form dimmers, trimmers, mixtures and tetramer. It can be used as high-octane fuel. Propylene and ethylene propylene rubber are generated. Propylene acid catalyst (sulfuric acid, hydrofluoric acid and the like) can become alkylation with isobutane to produce branched paraffin. Propylene in the presence of a catalyst with ammonia and oxygen in the air from the oxidation of ammonia to produce acrylonitrile, which can become a synthetic plastic, rubber, fiber and other polymer materials.

In the preparation of propylene tungsten trioxide prepare tungsten carbide powder, we make tungsten trioxide and propylene as raw material, the raw material is placed at 450 ℃ ~600 ℃. Then heating it after the mixed gas 90% Ar + 10% H2 at 1100 ℃ -1400 ℃ 2h, the material is crushed to obtain tungsten carbide powder .

Propylene tungsten trioxide prepares tungsten carbide powder, which improves the preparation of Chinese tungsten carbide powder level, and the obtained tungsten carbide powder can be used in production, which making China tungsten carbide powder resource advantages into economic advantages quickly, and makes a great contribution for China's export.
