Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 54 words
A method of making V 6 O 13+x wherein 0<x<2.0 comprising the steps of: in a stirred aqueous medium contained in a reaction vessel, slowly contacting V 6 O 13 with at least a nominal stoichiometric amount of hydrogen peroxide to form the product V 6 O 13+x wherein 0<x<2.0; and drying said product.
Claim 2
Independent Claim 54 words
A method of making V 6 O 13+x wherein 0<x<2.0 comprising the steps of: in a stirred aqueous medium contained in a reaction vessel, slowly contacting V 6 O 13 with at least a nominal stoichiometric amount of hydrogen peroxide to form the product V 6 O 13+x wherein 0<x<2.0; and drying said product.
Claim 3
Dependent Claim 37 words
The method of claim 1 wherein an aqueous solution of H 2 O 2 is added slowly to said stirred aqueous medium containing V 6 O 13 over a period of about 4 to about 12 hours.
Claim 4
Dependent Claim 20 words
The method of claim 2 further comprising the step of applying a stream of oxygen to said stirred aqueous medium.
Claim 5
Dependent Claim 15 words
The method of claim 3 wherein the product produced is V 6 O 13 .8.
Claim 6
Dependent Claim 15 words
The method of claim 3 wherein the product produced is V 6 O 14 .2.
Claim 7
Dependent Claim 17 words
The method of claim 1 wherein a stream of oxygen is added to said stirred aqueous medium.
Claim 8
Dependent Claim 21 words
The method of claim 1 wherein said reaction vessel is maintained at temperature of about 0° C. to about 45° C.
Claim 9
Dependent Claim 17 words
The method of claim 1 wherein said reaction vessel is sealed to maintain a constant volume reaction.
