  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。

  A liquid phase microextraction (LPME) method was developed for the determination of sulfur compounds in crude oils and its fractions (e.g diesel). Wide ranges of sulfur compounds including benzothiophene, dibenzothiophene and their derivatives were used as model compounds for extraction. After extraction, the analyses were performed by gas chromatography equipped with sulfur chemiluminescence detector (GC-SCD). Various experiments conditions influencing the extraction such as extraction times, extraction solvents, solvent volume and quantitative parameters were optimized to achieve higher extraction efficiency and high accuracy. The optimized conditions were applied to the determination of sulfur compounds in crude oil and diesel.
