摘要：

The vapor-phase reaction of methanol with isobutene to form MTBE (methyl tert-butyl ether) was carried out using titanium-modified silicalites at 70-110-degrees-C under atmospheric pressure, and the results were compared with those obtained using HZSM-5. The acid sites responsible for MTBE synthesis were mainly of weak to medium acid strength. MTBE synthesis reaction kinetic data could be fit with the Langmuir-Hinshelwood mechanism, which assumes the reaction between adsorbed methanol molecules with isobutene adsorbed at two different acid sites is the rate-determining step.
