The present invention provides selective extraction of sulfoxides, or sulfoxides in combination with sulfones, from hydrocarbon mixtures containing these compounds. A significant advantage of the invention is that oxidation products resulting from oxidative desulfurization of hydrocarbon feedstocks are selectively extracted with minimum co-extraction of non-oxidized products such as valuable hydrocarbon fuel components.
本发明提供了从含有这些化合物的碳氢化合物混合物中选择性萃取
硫氧化物或
硫氧化物与砜类化合物的方法。本发明的一个显著优点是可以选择性地萃取烃类原料氧化脱
硫过程中产生的氧化产物,同时将非氧化产物(如有价值的烃类燃料成分)的共萃取率降到最低。
