ETBE desulfurization extraction agent and desulfurization process

The invention belongs to the technical field of ether product production, and particularly relates to an ETBE desulfurization extraction agent and a desulfurization process. The ETBE desulfurization extraction agent comprises a sulfide complexing agent, a solvent and a scorch retarder. The sulfide complexing agent contains one or more than two of dimethyl formamide, dimethyl sulfoxide, N-methyl pyrrolidone and sulfolane; the solvent contains at least one of toluene, ethylbenzene, xylene or gasoline; the scorch retarder contains at least one of 2, 5-di-tert-butylhydroquinone, phenothiazine and ammonium sulfate. According to the ETBE desulfurization extraction agent and the desulfurization process, organic sulfides in ETBE can be effectively removed, and heavy components at the tower bottom are prevented from coking in the ETBE desulfurization process. 本发明属于醚类产品生产技术领域，具体涉及一种ETBE脱硫萃取剂及脱硫工艺。所述的ETBE脱硫萃取剂，包括硫化物络合剂、溶剂和防焦剂。硫化物络合剂含有二甲基甲酰胺、二甲基亚砜、N-甲基吡咯烷酮、环丁砜中的一种或两种以上；溶剂含有甲苯、乙苯、二甲苯或汽油中的至少一种；防焦剂含有2,5-二叔丁基对苯二酚、吩噻嗪、硫酸铵中的至少
