Title:
PRODUCTION OF UNSATURATED ALDEHYDE AND UNSATURATED CARBOXYLIC ACID
Document Type and Number:
Japanese Patent JP3267019
Kind Code:
B2
Abstract:

PURPOSE: To suppress the deterioration in performances of a catalyst and obtain the subject compound useful as a raw material, etc., for polymers by mixing a specific catalyst deteriorated in the performances with molybdenum oxide and reusing the resultant mixture as a catalyst and oxidizing propylene, t- butanol, etc., in the vapor phase.
CONSTITUTION: This method for producing the objective compound is to mix a compound oxide catalyst, deteriorated in performances by reaction and expressed by the formula [A is Ni or Co; B is Mn, Zn, Ca, Mg, Sn or Pb; C is P, B, As, Te, W, Sb or Si; D is K, Rb, Cs or Tl; (a) is 12; (b), (c), (d), (e) and (f) are each a positive number of ≤10; (g) is a positive number of ≤2; (x) is a constant determined by the oxidation states of the respective elements] with molybdenum oxide inert to the reaction, use the resultant mixture as a catalyst and catalytically oxidize propylene, isobutylene or t-butanol with molecular oxygen in the vapor phase.
