| 實驗中合成了仲鎢酸鹽X和帶兩缺陷的硅鎢雜多酸鹽Y兩種雙親性催化劑,利用紅外、紫外、單晶衍射和熱重等表征手段確定其結(jié)構(gòu)。通過對模擬柴油的氧化脫硫發(fā)現(xiàn),在適宜的操作條件下(50℃溫度,氧硫比等于5/1),乳液體系對不同種類,不同濃度的有機硫化物均具有良好的氧化效果,且二苯并噻吩及其衍生物比苯并噻吩及其衍生物更容易被氧化;氧化反應(yīng)速率隨著硫化物濃度的升高而加快。 |

In oxidative desulfurization of the model diesel compound, the emulsion system has good performance on different types of organosulfides with different concentrations at the optimal reaction conditions (50C, O/S = 5/1), and the dibenothiophene and derivatives are more readily oxided than the benzothiophene and derivatives, in the meantime, th oxidation reaction rate increases with the increase of the sulfur concentration. |

Dual amphiphilic catalyst, paratungstate X and heteropoly acidic salts Y with two defects were synthesized. IR, UV, single crystal diffraction and TG were used to investigate the structure. After the oxidation sweetening simulation of diesel oil, it was found that emulsion systems had good oxidation effect on organic sulfide of different types and concentration, dibenzothiophene and its derivatives were more easily oxidized than benzothiophene and its derivatives, and the rate of oxidation reaction was accelerated as the sulphide concentration increased under the appropriate condition (50 ℃, O:S mole ration 5:1). 僅供參考。 |
