MgO在WO3/SiO2催化烯烃歧化反应中的作用
Role of MgO in WO3/SiO2-catalyzed olefin metathesis reaction
摘要
Abstract
This paper reviews the progress of heterogeneous W-based catalysts used for olefin metathesis and introduces the research progress of olefin metathesis catalyst and metathesis reaction mechanism. This review focuses on the role of MgO aid in WO3/SiO2 catalytic propylene metathesis reaction,such as generating active gas-phase“excited species”,promoting double bond isomerization, adjusting acidity to reduce side effects and adsorbing poisons to purify the raw material,etc. In addition,this paper also presents the research trend of heterogeneous MgO-WO3/SiO2 metathesis catalysts to provide guidance and reference for development of highly active MgO-WO3/SiO2 catalytic systems.关键词
