Novel proton type beta zeolite, preparation method thereof and process for preparing phenol compound using the same

摘要

Disclosed are a proton type beta 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 mumol/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 beta zeolite.
