| titleOfInvention | Process for the manufacture of pure vanadium oxytrichloride |
| abstract | Pure vanadium oxytrichloride is prepared by reacting either pure VCl4 or crude VOCl3, containing VCl4 \sB VCl3 as sole vaporizable impurities, in the vapour state with O2 or a gas containing molecular O2, e.g. air, at a temperature of at least 200 DEG C., preferably at least 300 DEG C., but preferably less than 400 DEG C., and preferably at atmospheric pressure. It is preferred to condense VOCl3 in a column head withdraw a portion as product and return the remainder as reflux directly to the distillation vessel without passing into the reaction chamber. In an example 250 gm. VOCl3 containing 10% VCl4 were treated with air, entering the reactor at 200 DEG -300 DEG C. and 40-50 litres per hour, and heated to 300 DEG C. The crude VOCl3 was condensed quantitatively to pure VOCl3. |
