A method for producing an oxidation product by oxidizing a raw material compound in the presence of oxygen, wherein the raw material compound is oxidized in the presence of manganese dioxide having a crystal structure of β-type.
A catalyst for oxidation reaction, comprising manganese dioxide having a crystal structure of β-type.
A method for producing manganese dioxide, comprising the following steps:
- (1) mixing sodium permanganate and a strong acid salt of manganese(II) ion in water and stirring them;
- (2) collecting a precipitate after the step (1);
- and
- (3) calcining the precipitate collected in the step (2), wherein a specific surface area of the manganese dioxide is 50 m2g−1 or more.
