首先介绍了环丁砜的特点，综述了近几年国内外环丁砜在石油炼制中对饱和烃与芳香烃的萃取及其液液相平衡的研究现状。环丁砜在萃取提取重整油中的苯、甲苯和二甲苯等芳香烃表现出了很好的性能。环丁砜萃取工艺在工业上的应用已经很普遍，但也存在一些问题。因此，需要进一步研发完善环丁砜萃取剂，针对环丁砜在工业萃取方面的应用进行了详细阐述。

Characteristics of sulfolane were introduced, and research status of sulfolane used in the extraction of saturated hydrocarbons and aromatic hydrocarbons, liquid-liquid phase equilibrium at home and abroad in recent years was summarized. The sulfolane shows good performance in the extraction of benzene, toluene and xylene. The sulfolane extraction process has been widely used in industry, but there are some problems. Therefore, the further research and development of improved sulfolane extraction agent are necessary. In this paper, application of the sulfolane in the extraction field was introduced.
