A methanethiol-to-olefins (MtTO) equivalent of methanol-to-olefins (MTO) chemistry is demonstrated. CHSH can be converted to ethylene and propylene in a similar manner as CHOH over SSZ-13 zeolite involving a hydrocarbon pool mechansim. Methylated aromatic intermediates were identified by C NMR analysis. Comparison of MtTO and MTO chemistry provides clues about the mechanism of C-C bond formation and catalyst deactivation.
展示了一种与甲醇制烯烃（MTO）化学相当的甲硫醇制烯烃（MtTO）过程。与甲醇在SSZ - 13沸石上通过烃池机理转化为乙烯和丙烯的方式类似，甲硫醇（CHSH）也可转化为乙烯和丙烯。通过碳核磁共振（C NMR）分析鉴定出了甲基化的芳烃中间体。对MtTO和MTO化学的比较为碳 - 碳键形成机理和催化剂失活提供了线索。
