Cleave the bond: Zeolite depolymerized β-guaiacyl ether to produce monomers (≈87 %). Identification of various products reveals the crucial role of hydrogen, water, and acid sites in the heterolytic cleavage of the β-O-4 bond. Mechanistic analysis reveals that dehydration, decarbonylation, and hydrogenolysis were the main reactions taking place along with demethylation and hydrogenation.
键断裂:沸石解聚 β-愈创木醚产生单体 (≈87 %)。各种产物的鉴定揭示了氢、水和酸性位点在 β-O-4 键的异裂解中的关键作用。机理分析表明,脱水、脱羰基和氢解是与去甲基化和加氢反应同时发生的主要反应。
