Abstract
Ring-opening and dimerization reactions of methyloxirane and cis and trans 2,3- dimethyloxirane were studied on HZSM-5 zeolite in a closed static recirculation reactor at 363 K in reductive atmosphere. On this acidic material various reaction types could be observed. For methyloxirane the major transformation pathways were the acid-catalyzed ring opening and dimerization producing various dioxolane and dioxane derivatives. In addition to these routes 2,3-dimethyloxiranes underwent deoxygenation and rearrangement as well. Moreover, the activities and selectivities of the stereoisomers towards these pathways were found to be significantly different. Suggestions for transformation mechanisms are also offered.
