Vacuum pervaporation experiments were conducted to recognize the efficiency of organosulfur compounds (OSCs) separation from gasoline using com. hydrophobic membranes. Three of typically presented in gasoline sulfur species, i.e. thiophene, 2-methylthiophene and 2,5-dimethylthiophene, were selected to investigate the different sulfur compounds removal efficiency from n-octane/sulfur species used as a model gasoline. The influence of process parameters such as feed temperature, feed concentration on OSCs removal from model n-octane/sulfur compound mixtures was also examined During the test, the com. hydrophobic PEBA-based and PDMS-based composite membranes were applied. Conducted experiments with chosen sulfur species confirmed that the structure of a component and the resulting differences in the affinity toward tested membrane and physico-chem. properties can influence the membrane performance and led to different separation efficiency. Total fluxes for n-octane/thiophene, n-octane/2-methylthiophene and octane/2,5-dimethylthiophene mixtures at 30 °C were equal to be 1.33, 1.42 and 1.29 kg/m2 h in case of PEBA membrane and 7.21, 7.48 and 7.34 kg/m2 h for PDMS-base membrane, with the corresponding separation factor β values of 7.04, 3.95 and 1.25 for PEBA and 2.95, 1.56 and 1.01 for PDMS, resp. The intrinsic selectivity for thiophene/n-octane mixture (αT/O) also indicated that PEBA membrane (αT/O ≈ 18) is much more selective than PDMS one (αT/O ≈ 7.5). This study involved multiple reactions and reactants, such as 2,5-Dimethylthiophene (cas: 638-02-8Recommanded Product: 638-02-8).
2,5-Dimethylthiophene (cas: 638-02-8) belongs to benzothiophene derivatives. Functionalized benzothiophenes are important constructs found in molecules with wide ranging biological activity and in organic materials. It is found within the chemical structures of pharmaceutical drugs such as raloxifene, zileuton, and sertaconazole, and also BTCP.Recommanded Product: 638-02-8
