Titanium silicalite (TS-1) as catalyst has been used to epoxide propylene by hydrogen peroxide in a fixed-bed reactor. Experiments have shown that the hydrogen peroxide efficiency approaches 94% and the selectivety to propylene oxide is about 90% under the operation conditions of temperature 50～70 ℃, pressure of the reaction system 3.0 MPa, propylene to hydrogen peroxide(mol) 2.0～3.0, and the LHSV of propylene 2.0 h-1.
