Title:
CATALYST FOR OXIDATION OF METHYLBENZENES AND METHOD FOR PREPARATION OF AROMATIC ALDEHYDE
Document Type and Number:
Japanese Patent JP3737028
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a novel catalyst for preparing a corresponding aromatic aldehyde in a high yield by conducting a vapor-phase oxidation of methylbenzenes in the presence of molecular oxygen, and provide a method for preparation of an aromatic aldehyde by using the catalyst, and further a method for preparation of cyclohexane dimethanol by hydrogenation of phthalaldehydes obtained by the above method.
SOLUTION: The catalyst for oxidation of methylbenzenes has a composition expressed by general formula 1, WaXbYcOx, (wherein W represents a tungsten atom; X represents at least one element selected from the group consisting of P, Sb, Bi, and Si; Y represents at least one element selected from the group consisting of Fe, Co, Ni, Mn, Re, Cr, V, Nb, Ti, Zr, Zn, Cd, Y, La, Ce, B, Al, Tl, Sn, Mg, Ca, Sr, Ba, Li, Na, K, Rb, and Cs; and O represents an oxygen atom).
