ABSTRACT:
Disclosed are a proton type β zeolite in which an acid site showing a desorption peak with a range of ±100° C. with a center of 330° C. exists in a spectrum measured by the ammonia temperature programmed desorption method (NH3-TPD), and an amount of a strong acid site showing a desorption peak of 500° C. or higher is controlled to 2.5 μmol/g or less, a method for preparing the same, and a process for preparing a phenol compound by oxidizing a benzene compound with a peroxide in the presence of the proton type β zeolite.
