Claim 10
Dependent Claim
171 words
A process for producing a halo derivative of a vanadium organophosphate composition which comprises reacting in an aqueous solution a vanadyl salt wherein the vanadium is in its tetravalent form with a salt of an organophosphoric and, said salt having the formula: M(OP(O)w(R1O)x(OR2)y)2 wherein M is beryllium, magnesium, calcium, zinc, strontium, cadmium, barium or mixtures thereof, R1 is hydrogen, an alkyl or cycloalkyl having 1 to 16 carbon atoms or an aryl having up to 16 carbon atoms, R2 is a haloalkyl, pseudohaloalkyl, halocycloalkyl or pseudohalocycloalkyl, having 1 to 16 carbon atoms or a haloaryl or pseudohaloaryl having up to 16 carbon atoms, said halo being fluoro, chloro, iodo or bromo and said pseudohalo being cyano, cyanato or hydroxyl, w has a value of 0 or 1, x has a value of 0 or 1, y has a value of 1 or 2 and the sum of x and y is 2, at a temperature in the range of 0* to 200*C and recovering the resulting product from the aqueous solution.
