摘要 以咪唑及其衍生物和四丁基溴化铵(Bu4NBr)为原料,通过低温共熔合成3种低共熔溶剂(DESs),采用红外光谱和核磁氢谱对其进行表征,并考察DESs对模拟油品中二苯并噻吩的萃取性能。采用正交试验法详细考察了萃取温度、原料配比、油剂体积比、萃取时间和搅拌速率等因素对脱硫率的影响,从而确定最优萃取条件。分别计算出3种DESs多级逆流萃取脱硫的理论级数,在最优条件下进行多级反应,计算DESs的多级萃取脱硫率。结果表明:在萃取温度T为20℃、咪唑与Bu4NBr的物质的量之比X=0.6、油剂体积比为6、萃取时间t=30min、搅拌速率为600r/min的条件下,此种DES对二苯并噻吩的一次脱硫率达到89.2%,采用三级逆流萃取脱硫后,脱硫率达到98.08%。

Abstract: Three kinds of deep eutectic solvents (DESs) were synthesized by low temperature eutectic synthesis using imidazole and its derivatives as well as Bu4NBr.The samples were characterized by FT-IR and 1H-NMR.The effects of DESs on the extraction performance of dibenzothiophene in simulated oil.The effects of extraction temperature,ratio of raw materials,ratio of oil to oil,extraction time and stirring rate on desulfurization rate were investigated by orthogonal experiment.The optimum extraction conditions were determined.The desulfurization rate of DESs was calculated by multi-stage reaction under the optimal conditions.The desulfurization rate of DESs was calculated.The results showed that when the extraction temperature T was 20℃,the ratio of imidazole to Bu4NBr was X=0.6,the oil volume ratio was 6,the extraction time t=30min,and the stirring rate was 600r/min.The desulfurization rate of dibenzothiophene reached 89.2%,and the desulfurization rate reached 98.08% after three-stage desulfurization.
