The reaction proceeds near 600 °C:[5] Heating an intimate (well-blended with tiny particles) mixture of V2O5, chlorine, and carbon at 200–400 °C also gives VOCl3.In this case the carbon serves as a deoxygenation agent akin to its use in the chloride process for the manufacturing of TiCl4 from TiO2.Vanadium(III) oxide can also be used as a precursor:[2] A more typical laboratory synthesis involves the chlorination of V2O5 using SOCl2.[6] VOCl3 quickly hydrolyzes resulting in vanadium pentoxide and hydrochloric acid.VOCl3 is strongly Lewis acidic, as demonstrated by its tendency to form adducts with various bases such as acetonitrile and amines.
