Procedure
A slurry was prepared of 86.4 (0.06 mole Mo) of molybdenum trioxide and 7.6 g. (0.067 mole P) of 85% phosphoric acid in 500 mls. of distilled water; boiled with stirring for three hours to form phosphomolybdic acid which was yellowish green in color. To this slurry was added 2.5 g. (0.0125 mole Cu) of copper acetate; no change in color, followed by the addition of 7.9 g. (0.025 mole Bi) of bismuth chloride dissolved in 4.0 ml. of concentrated hydrochloric acid. The mixture was boiled to dryness; dried overnight at 110° C in air. The catalyst was ground and screened to 20/30 mesh fraction and calcined for three hours at 400° C in 40 ml/min. air.
