Patent ID: 7091365

Claim:
A process for olefin epoxidation comprising: contacting at least one olefin with cyclohexyl hydroperoxide under olefin epoxidation reaction conditions in the presence of a catalyst to provide an epoxidation reaction effluent containing olefin epoxide, wherein said catalyst comprises a transition metal and an amorphous porous inorganic oxide having randomly interconnected mesopores, wherein said mesopores range in diameter from about 1.5 to about 30 nm and comprise at least about 97 volume percent of the pore volume based upon mesopores and micropores, and wherein said porous inorganic oxide is characterized by an X-ray diffraction pattern having a peak between 0.50 and 3.00 in 2θ, and wherein said porous inorganic oxide has a surface area of from about 400 to 1,100 m 2 /g.
