氧氯化锆基低共熔溶剂的合成及其氧化脱硫性能
Synthesis of Zirconium Oxychloride-Based Deep Eutectic Solvents and Their Oxidative Desulphurization Properties
摘要
Abstract
A zirconium oxychloride(ZOC)-based deep eutectic solvent(DES)was successfully prepared through thermal mixing of ethylene glycol(EG)with ZOC.The structure of the DES was systematically characterized using FT-IR and ¹H NMR,confirming its successful synthesis,while its viscosity was determined using a rotational viscometer.An extraction-oxidation coupled desulfurization system was constructed using hydrogen peroxide as the oxidant and the DES as both an extractant and a catalyst.The effects of DES composition,reaction temperature,oxygen-to-sulfur molar ratio,solvent-to-oil mass ratio,and different types of sulfides on the desulfurization rate were systematically investigated.The results demonstrated that under optimal conditions(zirconyl chloride to ethylene glycol molar ratio of 1∶24,reaction temperature of 50℃,solvent-to-oil mass ratio of 1∶5,and oxygen-to-sulfur molar ratio of 8),the system achieves a desulfurization rate of 99.8%,94.0%,and 69.8%for dibenzothiophene(DBT),4,6-dimethyldibenzothiophene(4,6-DMDBT),and benzothiophene(BT)in model oil,respectively.Notably,the DES maintains a desulfurization rate of 94.9%after five reuse cycles,demonstrating excellent recyclability.Through experimental data analysis,the reaction mechanism was further elucidated,revealing the synergistic mechanism of DES in both sulfide oxidation and extraction processes.关键词
