ABSTRACT:
Vanadium oxytrihalide (e.g., VOCl.sub.3) is reacted with alkali metal alkoxide (e.g., NaOEt) in the presence of a diluent (e.g., EtOH) that boils below the boiling point of the organic vanadate being produced. The diluent is then distilled from the reaction mixture and thereafter the organic vanadate is distilled from a suspension of the reaction products in an inert liquid hydrocarbon (e.g., mineral oil) that boils above the boiling point of the organic vanadate produced. This higher boiling hydrocarbon is preferably added to the reaction mixture after the diluent has been distilled off. The process avoids hydrogen halide evolution and consequent need for gaseous ammonia. Solvent extractions are not required, the process may be conducted in a single reactor, and the products are readily formed in high yields.
