| Hazard Information | Back Directory | [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] | [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.
