在工业中,醇氧化成醛是一个重要的反应,目前以离子液体负载小分子有机催化剂对醇的均相氧化研究较多,但其可回收再利用性较低。以聚丙烯腈(PAN)基碳纤维原丝废丝为原料,通过对废丝的处理,将其作为离子液体的阴离子,并成功将离子液体负载于PAN基碳纤维原丝废丝上,实现了在非均相反应中的均相反应,并为方便分离催化剂和重复利用催化剂提供了一种可能。
In industry, the oxidation of alcohols to aldehydes is an important reaction. Currently, there are many studies on the homogeneous oxidation of alcohols with ionic liquid supported small organic catalysts, but their recyclability is low. Using polyacrylonitrile (PAN) -based carbon fiber yarn as raw material, the waste silk is treated as an anion of the ionic liquid and the ionic liquid is successfully loaded on the waste of the PAN-based carbon fiber precursor yarn, Homogeneous reaction in heterogeneous reaction and provides a possibility for facilitating catalyst separation and catalyst reuse.
