摘要：

Titanium silicalite-1 catalyst was prepared using a SiO2-TiO2 xerogel and applied to allylchloride (ALC) epoxidation by H2O2 as oxidant in a batch reactor. The reaction temperature was varied from 25 to 55 degrees C, and the concentrations of ALC and H2O2 were changed from 0.2 to 3 M and from 0.2 to 1.5 M, respectively. The kinetic data obtained were applied to the power rate law, Eley-Rideal, and a Langmuir-Hinshelwood model, and power rate law fits the experimental data best. Activation energy was 27.9 kJ/mol, and the reaction orders with respect to H2O2 and ALC were determined to be 0.41 and 0.52, respectively.
