Abstract

Provided is a process of conducting olefin epoxidation which comprises contacting an olefin and an oxidant in the presence of Ti-UCB-4 to thereby prepare an epoxide. The Ti-UCB-4 catalyst is prepared by delaminating a B-SSZ-70 precursor and substituting Ti atoms for the boron atoms on the surface of the zeolite material lattice framework.
