摘要

开发用分子氧制备环氧丙烷(PO)的绿色方法在学术界和工业界都具有重要意义。本研究开发了铂介四苯基卟啉(Pt (II)TPP)催化的丙烯环氧化与糠醛氧化反应。丙烯转化率和 PO 选择性分别高达 56% 和 83%。同时,糠醛几乎完全转化为糠酸。根据操作表征和电子顺磁共振(EPR)测试,提出了一种涉及高价铂物种的机理。这项工作有望为化工行业同时生产 PO 和呋喃酸提供潜在的应用前景。

Propylene epoxidation coupled with furfural oxidation over Pt (II)TPP porphyrin with molecular oxygen

The development of green route for preparing propylene oxide (PO) with molecular oxygen is of significance both in academic and industrial. In this work, propylene epoxidation coupled with furfural oxidation catalyzed by platinum meso-tetraphenylporphyrin (Pt (II)TPP) has been developed. Propylene conversion and PO selectivity reached up to 56% and 83%, respectively. Meanwhile, furfural was almost completely converted to furoic acid. Based on operando characterizations and electron paramagnetic resonance (EPR) tests, a mechanism involved high-valent Pt species was proposed. This work is expected to provide a potential application prospects for producing PO and furoic acid simultaneously in chemical industry.
