Abstract
<FORM:0902233/III/1> ZrCl4, TaCl5, MoCl5 and WCl6 are made by direct synthesis from their elements using the apparatus shown in Fig. 5. A quantity of metal is placed in reaction tube 150 and argon introduced through conduit 156 while the tube is being brought to reaction temperature by furnace 152. When such temperature is reached, chlorine is introduced through conduit 158 and the resulting metal chloride collected in cooled flask 160. VCl4 is made by reaction in an electrically-heated flask between vanadium and chlorine, the resulting chloride being distilled off into a cooled receiving flask which is open to the atmosphere through a CaCl2 drying tube. TiCl4 is purified by refluxing with Cu gauze and then distilling through a Vigreaux column. Anhydrous CrCl3 is made by dehydrating CrCl3,6H2O with CCl4 at a temperature increasing from 150 DEG to 650 DEG C. Anhydrous MnCl2 is made by vacuum dehydrating the tetrahydrate in an electrically heated evacuated flask, the water being collected in an ice trap.
