| 摘 要： | 以四甲基乙二胺和溴代十六烷为原料,合成了一种季铵盐双子表面活性剂,简记为TTL(16-2-16),其表面活性cmc=0.1mmol/L,γcmc=32.5mN/m;TTL(16-2-16)做为相转移催化剂加入到H2O2/CH3COOH体系中,优化得到了催化氧化脱硫的适宜反应条件:V(H2O2)∶V(CH3COOH)=3∶1,V(氧化体系)∶V(柴油)=1∶1,反应时间为60min,反应温度为45℃,TTL(16-2-16)的用量为0.25%,在此条件下的柴油的硫含量可降至44μg/g,脱硫率为94.0%。

| Abstract: | A kind of quaternary ammonium Gemini surfactant,denoted as TTL(16-2-16),was synthesized taking tetramethyl ethylenediamine(CTAB) and 1-bromohexadecane as raw materials.The results showed that cmc(0.1mmol / L) of TTL(16-2-16) was 1 / 10of the corresponding surfactant(CTAB) andγ cmc was 32.5mN / m,which was 8mN / m less than CTAB.TTL(16-2-16) was added to the H 2 O 2 / CH 3 COOH system as phase transfer catalyst and optimized reaction conditions of catalytic oxidation desulfurization were obtained as follows : V(H 2 O 2) ∶ V(CH 3 COOH) = 3 ∶ 1,V(oxidation) ∶V(diesel) =1∶1,the reaction time and temperature were 60min and 45℃respectively,TTL(16-2-16) was 0.067%.The sulfur content of diesel fuel under these conditions could be decreased to 44 μ g / g and the desulfurization rate could be up to 94%. |
