  表面活性剂胶束对四硝基甲烷与氢氧化物离子反应速率的影响

  摘要：

  在水溶液中存在阴离子、阳离子和非离子表面活性剂胶束的情况下测量四硝基甲烷与氢氧根离子反应形成三硝基甲烷阴离子的速率。使用考虑疏水反应物在胶束中分布的分析方法，k1（与一个反应物分子相关的胶束的二阶速率常数）和 K1/N（K1：反应物与没有反应物的胶束的缔合常数，N：估计胶束中表面活性剂分子的聚集数）。阴离子表面活性剂对反应速率没有影响。在阳离子表面活性剂的情况下，k1 和 K1 值不仅随着烷基链长度的增加而且随着表面活性剂的疏水性而增加。在非离子表面活性剂的情况下，

The kinetic data have shown that, for 16-3-16,2NO3− and CTAN, at a surfactant concentration below the critical micelle concentration (cmc) the rate of the complex formation reaction does not significantly depend on the surfactant concentration, while it slightly decreases in the presence of the other two gemini surfactants. Beyond this critical value, in all cases examined

• CoMoW sulfide nanocatalysts for the HDS of DBT from novel ammonium and alkyltrimethylammonium-thiomolybdate-thiotungstate-cobaltate (II) precursors

  Five unsupported, highly active CoMoW trimetallic nanocatalysts were obtained by in situ decomposition from five novel precursors: (NH4)(2)[Co(MoS4)(WS4)] and (RN(CH3)(3))(2)[(MoS4)(WS4)] (where R = dodecyl, tetradecyl, cetyl and octadecyl), during the HDS of DBT. The catalyst labeled CoMoWS-C14, derived from the precursor containing the tetradecyl group, exhibits the highest catalytic activity (k = 421 x 10(-7) mol/g s). N-2 adsorption-desorption shows that the CoMoW catalysts are mesoporous materials with characteristic Type IV isotherms, having surface areas of 11-340 m(2)/g. Elemental analysis by X-ray energy dispersive spectroscopy (EDS) working at STEM mode finds high concentrations of carbon (3.7 <= C/Mo <= 11.3 and 2.7 <= C/W <= 9) in all the catalysts except CoMoWS, where carbon was not detected. The XRD patterns show that the catalysts are highly dispersed (less so for the CoMoWS) given the absence of the (0 0 2) reflection, along with broad and low intensity (1 0 1) and (1 1 0) reflections. High dispersion is also supported by the STEM micrographs showing unstacked layers. The selectivity of the reaction for all catalysts favors the direct desulfurization pathway. The surface area and high catalytic activity do not show direct correlation with the length of the hydrocarbon chains of the precursors. (C) 2014 Elsevier B.V. All rights reserved.
