バナジウム(IV)テトラフルオリド 化学特性,用途語,生産方法

• 化学的特性

  green to brown powder

• 使用

  Vanadium(IV) fluoride is an important raw material and intermediate used in organic synthesis, pharmaceuticals and agrochemicals.

• 調製方法

  Freshly distilled, Dry Ice-cooled VCl4 (40 g) is added to 130 g of similarly cooled anhydrous HF contained in a reactor. A copper reflux condenser charged with a cooling mixture is then attached to the vessel, and the reaction mixture is allowed to warm slowly to 0°C. The mixture is then boiled for several hours until no further HCl evolves. The reflux condenser is then replaced by a descending condenser, and the HF is distilled off. The VF4 remaining in the reactor is freed of any traces of HF by passing a dry stream of nitrogen at 50°C. The yield is 97%, based on VCl4. The product may be stored in sealed iron or copper containers.
