Technique for extracting and washing sulfurized isobutene

This invention discloses a process for extracting isobutylene sulfide with methanol as the extractant. Compared with the present technique (using 120# gasoline as the extractant), this process has such advantages as low extractant consumption, easy recovery, and high isobutene yield.
