Abstract

A polymeric support based on a poly(azomethine) (PAM) structure was synthesized using mechanochemical polymerization (PAM@M) and compared with its counterpart prepared via conventional high-temperature solution-phase polycondensation (PAM@T). The mechanochemical approach not only significantly reduced the synthesis time (1 hour versus 24 hours), but also resulted in a polymer with amorphous character while the one synthesized via conventional heating exhibits some crystalline peaks. FePAM@M demonstrated superior catalytic performance with complete conversion of glycerol to solketal with 100% selectivity in only 1 hour at room temperature, exhibiting an impressive environmental factor (E-factor = 3.49). The conversion of glycerol into value-added products is essential due to its large-scale generation as a by-product of biodiesel, so the results of this work highlight FePAM@M as a highly efficient and sustainable catalyst for this valorisation.

聚亚甲胺的机械化学合成：甘油增值过程中金属载体的可持续载体

采用机械化学聚合法合成了一种基于聚亚甲胺（PAM）结构的聚合物载体（PAM@M），并与传统高温液相缩聚法制备的聚合物载体（PAM@T）进行了比较。机械化学方法不仅大大缩短了合成时间（1小时比24小时），而且产生的聚合物具有无定形特征，而通过传统加热合成的聚合物则呈现出一些结晶峰。FePAM@M表现出优异的催化性能，在室温下仅1小时就能100%选择性地将甘油完全转化为索酮，表现出令人印象深刻的环境因素（E-factor = 3.49）。由于甘油作为生物柴油的副产品大规模生产，因此将其转化为增值产品是必不可少的，因此这项工作的结果突出了FePAM@M作为这种增值的高效和可持续催化剂。
