titleOfInvention | New proton type β zeolite |
abstract | An object of the present invention is to provide a novel proton-type β zeolite which is easy to prepare and exhibits high reactivity even at a low temperature, and to oxidize monohydric phenols using the same to obtain a dihydric phenol in high yield. To provide an industrial production method for producing such products. An object of the present invention is to provide an ammonia thermal desorption spectroscopy (NH 3 -TPD) having an acid point having a desorption peak in a range of ± 100 ° C. around 330 ° C., and A novel proton-type β zeolite having an amount of strong acid sites exhibiting a desorption peak of 500 ° C. or higher of 2.5 μmol / g or less, and a monohydric phenol is oxidized using the zeolite to obtain a high yield. The problem is solved by an industrial method for producing dihydric phenols for producing polyhydric phenols. [Selection diagram] None |
