  胆碱能阴离子受体III

  摘要：

  为了识别胆碱能阴离子受体的某些优良特性，最初的研究是对乙酰胆碱酯酶抑制剂的研究，该抑制剂使用的是相对无构象变化的抑制剂。所用的抑制剂是季铵化的1-氮杂双环（2.2.2）辛烷。双环母体胺通过几种常规方法制备。通过滴定法将这些盐评价为乙酰胆碱酯酶的竞争性抑制剂。将这些化合物对该酶的阴离子位点的亲和力与一系列发生构象变化的相关盐的亲和力进行了比较。这些比较表明，该胆碱能受体的阴离子位点比迄今所怀疑的更具有立体化学要求。

• Odd–Even Effect and Unusual Behavior of Dodecyl-Substituted Analogue Observed in the Crystal Structure of Alkyltrimethylammonium–[Ni(dmit)₂]⁻Salts

  A series of [Ni(dmit)2]− (dmit: 1,3-dithiole-2-thione-4,5-dithiolato) salts of alkyltrimethylammonium (Cn: n represents the alkyl chain length; n = 3 and 5–18) have been prepared and analyzed by X-ray structural analysis. All complex salts have been found to be composed of alternate sheets of [Ni(dmit)2]− anions and sheets of cations with a pronounced interdigitation of the alkyl chains. However, molecular arrangement differed between (C3)[Ni(dmit)2] and other (Cn)[Ni(dmit)2] (n = 5–18). Adjacent cations were aligned along the long axis of [Ni(dmit)2]− anion in C3 complex salt, while in others (C5–C18 complex salts), they were aligned toward the short axis. Such a difference in arrangement arose from correlativity between the lengths of the long axis of cation and anion, namely CLCA. Furthermore, relative orientation between the alkyl chain of cation and [Ni(dmit)2]− anion differed between the odd- and even-numbered cations for C10–C18. Whereas the plane of alkyl chain for odd-numbered cation was normal to the plane of [Ni(dmit)2]− anion, that of even-numbered cation was parallel. It was also found that C12 analog behaved like odd-numbered cations. However, in C12 salt, the end methyl group of the dodecyl group adopted unusual end-gauche conformation.

  一系列[Ni(dmit)2]−（dmit：1,3-二硫杂环戊烯-2-硫酮-4,5-二硫醇）的烷基三甲基铵盐（Cn：n代表烷基链长度；n = 3和5–18）已被制备并通过X射线结构分析进行了研究。所有复合盐均被发现由交替的[Ni(dmit)2]−阴离子层和阳离子层组成，阳离子层的烷基链存在显著的互插结构。然而，分子排列在(C3)[Ni(dmit)2]和其他(Cn)[Ni(dmit)2]（n = 5–18）之间有所不同。在C3复合盐中，相邻的阳离子沿[Ni(dmit)2]−阴离子的长轴排列，而在其他（C5–C18复合盐）中，它们朝向短轴排列。这种排列差异源于阳离子和阴离子长轴长度的相关性，即CLCA。此外，对于C10–C18，阳离子烷基链与[Ni(dmit)2]−阴离子之间的相对取向在奇数和偶数编号阳离子之间有所不同。奇数编号阳离子的烷基链平面垂直于[Ni(dmit)2]−阴离子平面，而偶数编号阳离子的烷基链平面则平行。还发现C12类似物表现得像奇数编号阳离子。然而，在C12盐中，十二烷基的末端甲基采取了不寻常的末端-旁式构象。

  A method for co-production of high purity dimethyl carbonate and mono-ethylene glycol by applying a reactor, such as a membrane reactor and/or an adsorbent-catalytic reactor by capturing and reacting carbon dioxide with methanol and ethylene oxide. Carbon dioxide may be recovered from primary sources (utilities and industrial processes) by a membrane or solid adsorbent, and subsequently converted to an intermediate hydroxy-ethyl-methyl carbonate by reacting with ethylene oxide and methanol. For high-purity carbon dioxide (obtained by carbon capture technologies or from an ethanol fermentation process), the membrane reactor is replaced with a catalytic reactor for direct conversion of carbon dioxide to hydroxy-ethyl-methyl carbonate by reacting with ethylene oxide and methanol. The hydro-ethyl-methyl carbonate is further reacted with methanol for conversion to dimethyl carbonate. A combination of heterogeneous and homogeneous catalysts is implemented for an effective conversion of carbon dioxide. An integrated reactive distillation process using side reactors is used for facilitating catalytic reaction for production of high purity dimethyl carbonate.

  应用反应器（如膜反应器和/或吸附剂催化反应器）通过捕集和反应二氧化碳与甲醇和乙烯氧共同生产高纯度的碳酸二甲酯和单乙二醇的方法。二氧化碳可以从主要来源（公用事业和工业过程）通过膜或固体吸附剂回收，并随后通过与乙烯氧和甲醇反应将其转化为中间体羟乙基甲基碳酸酯。对于高纯度的二氧化碳（通过碳捕集技术或乙醇发酵过程获得），将膜反应器替换为催化反应器，直接将二氧化碳与乙烯氧和甲醇反应转化为羟乙基甲基碳酸酯。羟乙基甲基碳酸酯进一步与甲醇反应转化为碳酸二甲酯。采用异质和均相催化剂的组合实现二氧化碳的有效转化。使用侧反应器的集成反应精馏过程用于促进生产高纯度碳酸二甲酯的催化反应。
