Abstract:
1. A process for preparing a catalyst for partial oxidation of propylene and iso-butylene represented by the following Chemical Formula 1, which process comprises the steps of: a) dissolving a metal salt compound comprising i) a molybdenum salt, ii) a bismuth salt, iii) an iron salt, iv) one or more salts of metals selected from the group consisting of cobalt, tungsten, vanadium, antimony, and nickel, and v) one or more salts of metals selected from the group consisting of potassium, rubidium, and cesium, in a nitric acid aqueous solution or in an organic acid solution to prepare a catalyst suspension; b) drying the catalyst suspension of step a) in a microwave oven; c) pulverizing and molding the dried catalyst of step b) to prepare a catalyst powder; and d) calcining the catalyst powder obtained in step c), (wherein X is cobalt, tungsten, vanadium, antimony, or nickel, Y is potassium, rubidium, or cesium, each of a, b, c, d, and e represents the atomic mole ratio of each metal, and when a is 12, b is 0.5˜2, c is 0.5˜2, d is 3˜8, and e is 0.005˜0.2, and f is determined according to oxidation state of each metal).
