摘要

Process for the preparation of a catalyst adapted for use in the oxidation phase of catalytic vapor of isobutylene to methacrolein, characterized by comprising the preparation of an aqueous ammoniacal solution of a copper halide, a molybdate and a chromate, impregnated therewith an aqueous material, drying it and then activating it at a temperature in the order of about 400º to 500º C, for a time in the order of 5 to 25 hours, the proportions being such that in relation to the weight of the copper formula as 1, 0, the molybdenum formula weight is in the order of 0.05 to 2.0 and the formula weight of the chromium present is in the order of 0.05 to 2.0.
