Characterization of Sulfur Compounds in MTBE

Figure 2

Sulfur compounds generated from the simulation test. (a) Before reaction: methanol containing trace methanethiol and ethanethiol; (b) after reaction: MTBE synthesized by using isobutene and the methanol. (1) Methanethiol; (2) ethanethiol; (3) tert-butyl methyl sulfide; (4) dimethyl disulfide; (5) tert-butyl ethyl sulfide; (6) ethyl methyl disulfide; (7) diethyl disulfide.
