反応手順

A catalyst of the formula Mo12P1.32 Bi0.5 Cu0.25 Cl0.06 Of was prepared as follows: A slurry was prepared of 86.4 grams (0.60 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 10/30 mesh fraction.
