Identification of thiophenes in S-zorb gasoline by GC/Q-TOF MS was written by Ren, Xujin;Huang, Shaokai;Hu, Miao;Wu, Qing. And the article was included in Fenxi Shiyanshi in 2021.Category: benzothiophene The following contents are mentioned in the article:
Combined with gas chromatog. separation and tandem mass spectrometry screening technol., the target parent ions were selected for collision induced dissociation to obtain accurate ion fragments, which achieved trace screening of the thiophene compounds in gasoline fractions. Quant. standard curves were drawn according to five characteristic thiophene compounds and the direct anal. method of thiophenes (TPs) in S-zorb gasoline by GC/Q-TOF MS was established. The method was utilized to identify the TPs and the removal rule of them in S-zorb gasoline. The results showed that thiophene with Me on 2-position was more difficult to be removed than the one with Me on 3-position. The 2-, 5-two Me substituent groups and thiophenes with Me substituent groups on 2-, 3-, 5-position are the main remaining thiophene compounds of C2-TPs and C3-Tps. This study involved multiple reactions and reactants, such as 2,5-Dimethylthiophene (cas: 638-02-8Category: benzothiophene).
2,5-Dimethylthiophene (cas: 638-02-8) belongs to benzothiophene derivatives. Benzothiophene finds use in research as a starting material for the synthesis of larger, usually bioactive structures. It is also used in the manufacturing of dyes such as thioindigo.Category: benzothiophene
