Abstract

A novel catalyst was synthesized by immobilizing a MoO₂(acac)₂ complex on the surface of a porous aromatic framework functionalized with pyridine-2-carboxaldehyde (PAF-30-NPy). The immobilization was confirmed by IR spectroscopy, X-ray photoelectron spectroscopy, and elemental analysis. The synthesized catalyst was tested in the epoxidation of cyclohexene, cycloheptene, 1-hexene, 1-octene, styrene, and trans-stilbene. The effects of the solvent type and the oxidant content on the olefin conversion were described. The catalyst reusability was further tested, and its activity was evaluated.

多孔芳香族框架支撑的钼催化剂在烯烃环氧化中的应用

通过在吡啶-2-甲醛（PAF-30-NPy）功能化的多孔芳香框架表面固定 MoO2(acac)2 复合物，合成了一种新型催化剂。红外光谱、X 射线光电子能谱和元素分析证实了固定化效果。合成的催化剂在环己烯、环庚烯、1-己烯、1-辛烯、苯乙烯和反式二苯乙烯的环氧化反应中进行了测试。介绍了溶剂类型和氧化剂含量对烯烃转化的影响。还进一步测试了催化剂的可重复使用性，并对其活性进行了评估。

期刊介绍： Petroleum Chemistry (Neftekhimiya), founded in 1961, offers original papers on and reviews of theoretical and experimental studies concerned with current problems of petroleum chemistry and processing such as chemical composition of crude oils and natural gas liquids; petroleum refining (cracking, hydrocracking, and catalytic reforming); catalysts for petrochemical processes (hydrogenation, isomerization, oxidation, hydroformylation, etc.); activation and catalytic transformation of hydrocarbons and other components of petroleum, natural gas, and other complex organic mixtures; new petrochemicals including lubricants and additives; environmental problems; and information on scientific meetings relevant to these areas. Petroleum Chemistry publishes articles on these topics from members of the scientific community of the former Soviet Union.
