Title:
OXIDATION CATALYST AND OXIDATION USING THE SAME
Document Type and Number:
Japanese Patent JP3818829
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for efficiently oxidizing a cycloalkane under mild conditions in the absence of a specific reducing agent, or the like, by oxidizing the cycloalkane as a substrate with molecular oxygen in the presence of a specific compound and a cobalt compound.
SOLUTION: This method comprises oxidizing (A) a cycloalkane as a substrate with (B) molecular oxygen in the presence of (C) 0.001-1 mol, pref. around 0.05 to 0.25 mol, per mol of the component A, of an imide compound of the formula [R1 and R2 are each H, a halogen, a (cyclo)alkyl, an aryl, OH, an alkoxy(carboxyl), COOH or an acyl, or bound together to form a double bond or a (non)aromatic ring; X is O or OH; (n) is 1-3] as an oxidation catalyst (e.g. N-hydroxyphthalimide) and (D) a cobalt compound as a cooxidizing agent, in a molar ratio of the compound C to the compound D of (95:5) to (5:95), pref. (85:15) to (50):(50).
