  氢芳烃的碳 13 磁共振。二、四氢萘和四氢蒽及其甲基衍生物的构象

  摘要：

  已获得 36 种甲基化四氢萘和四氢蒽的碳 13 化学位移数据。对明确构象的化合物的环碳进行了最小二乘回归分析，以确定两个不同脂肪族位置的甲基取代参数，结果已用于估计构象移动化合物的平衡位置。得出的结论是，1-甲基萘满在室温下以基本相同的构象异构体存在，但 2-甲基衍生物主要由具有赤道甲基的构象支配。将取代基参数与先前为甲基化环己烷确定的参数进行比较。对甲基化学位移的类似分析没有成功，部分原因是饱和环的高度柔性。

  Nickel-tungsten sulfide nanocatalysts for the hydrogenation of aromatic hydrocarbons (HCs) have been prepared by the in situ decomposition of a nickel thiotungstate precursor in a HC feedstock using 1-butyl-1-methylpiperidinium nickel thiotungstate complex [BMPip](2)Ni[WS4](2) as the precursor. The in situ synthesized particles have been characterized by X-ray photoelectron spectroscopy and high-resolution transmission electron microscopy. It has been shown that the resulting Ni-W-S particles are nanoplates associated in multilayer agglomerates; the average length of the Ni-W-S particles is 6 nm; the average number of layers in the multilayer packaging is three. The catalytic activity of the synthesized catalysts has been studied in the hydrogenation of model mixtures of mono- and bicyclic aromatic HCs and in the conversion of dibenzothiophene in a batch reactor at a temperature of 350A degrees C and a hydrogen pressure of 5.0 MPa. It has been shown that the studied catalysts can be used for the hydrofining of light cycle oil.
