Procedure
A slurry was prepared of 86.2 g (0.6 mole) of molybdenum trioxide and 7.7 g. (0.67 mole P) of 85% phosphoric acid in 1500 mls. of distilled water; boiled with stirring for 2 hours to form phosphomolybdic acid which was greenish yellow in color. 2.3 g. (0.01 mole) of indium acetate was added to the slurry; no change in color, followed by the addition of 14.4 g. (0.1 mole) of rubidium acetate. The aqueous mixture which was yellow in color and was boiled to dryness; dried overnight at 110° C in air. The catalyst was ground and screened to 20/30 mesh fraction.
