This work reports a novel sustainable two-step method for the synthesis of ethylene glycol (EG) using syngas. In the first step, diethyl oxalate was selectively synthesized via oxidative double carbonylation of ethanol and carbon monoxide (CO) using a ligand-free, recyclable Pd/C catalyst. In the second step, the diethyl oxalate produced underwent subsequent hydrogenation using [2-(di-tert-butylphosphinomethyl)-6-(diethylaminomethyl)pyridine]ruthenium(II) chlorocarbonyl hydride to get EG and ethanol. Thus, the generated ethanol can be recycled back to the first step for double carbonylation. This method gives a sustainable route to manufacture EG using carbon monoxide and hydrogen.

乙醇氧化双羰基化合成草酸二乙酯由合成气合成乙二醇及其加氢反应

这项工作报告了使用合成气合成乙二醇(EG)的新型可持续两步法。在第一步中,使用不含配体的可回收Pd / C催化剂,通过乙醇和一氧化碳(CO)的氧化双羰基化选择性地合成草酸二乙酯。在第二步中,使用[2-(二叔丁基膦基甲基)-6-(二乙基氨基甲基)吡啶]钌(II)氯羰基氢化物氢化生成的草酸二乙酯,随后进行氢化,以得到EG和乙醇。因此,产生的乙醇可以再循环回到第一步以进行双羰基化。该方法为使用一氧化碳和氢气生产EG提供了可持续的途径。
