| | VANADIUM(II) CHLORIDE Usage And Synthesis |
| Chemical Properties | apple green; hexagonal plates; strong reducing agent; preparation: heating VCl3 in N2 atmospheric, followed by sublimation in N2 atmospheric; used to purify HCl by removing arsenic [HAW93] | | Uses | battery manufacturing | | reaction suitability | reagent type: catalyst
core: vanadium | | Synthesis | 
Rapid disproportionation of VCl3 according to the above equation
can be achieved at 800°C in a stream of high-purity N2. The VCl4 is carried away by the N2 stream (4 bubbles/sec), while the VCl2
remains in the reactor tube. The temperature should not exceed
850°C, to avoid loss of VCl2 by sublimation. The reaction is fairly
fast; for example, the reaction of 20 g. of VCl3 takes 2 hours. | | Solubility in organics |
Insoluble in alcohol or ether.
