  to alkaline media; however, very few investigations have systematically evaluated how these cations decompose in the presence of hydroxide or alkoxide anions. The excellent stability of several tetraaminophosphoniums in 2 M KOH/CH3OH at 80 °C led us to design experiments for the rapid assessment of phosphonium degradation in homogeneous solution and under phase-transfer conditions. The analysis illustrated

  氢氧化物稳定的有机阳离子是电化学能量系统中离子迁移过程的关键组成部分，四（二烷基氨基）阳离子是该应用的有希望的候选者。已知这些phospho对碱性介质具有高度的抵抗力。但是，很少有研究系统地评估这些阳离子在氢氧根或醇盐阴离子存在下的分解方式。几种四氨基phosph在2 M KOH / CH 3中的优异稳定性在80°C的OH下，我们设计了用于快速评估homogeneous在均相溶液中和相转移条件下降解的实验。分析表明，阳离子核心周围的取代基如何影响降解途径和降解速率。在醇溶剂中观察到最常见的降解途径是β-H的消除和对磷原子的直接侵蚀，而在相转移条件下（PhCl和50 wt％NaOH / H 2 O）则观察到α-H的提取和直接侵蚀。。收集的数据提供了该阳离子家族的相对稳定性比较，以实现将来的设计改进，并说明了使用多种测试进行降解研究的实用性。

  The effect of the lipophilicity and coordinating ability of neutral ligands, belonging to the classes of phosphoric amides and pyridine oxides, on the extraction of the neutral oxidants molybdenum(VI)–peroxo complexes from an aqueous acidic phase to an organic one, has been studied. The nature of the Mo(VI)–peroxo species present both in aqueous and organic phase has also been investigated. Sizable amounts of mineral acid, added to adjust pH, may be extracted into the organic phase. The various factors affecting this process such as the nature of the acid added, the organic solvent and the neutral ligand, as well as the effect of this feature on the partition of the oxidant between the two phases are briefly discussed.

We discuss the synthesis, purification, and characterization of two such hexaalkylphosphoramides (Propyl and Butyl) in this paper. Their physico-chemical properties were measured and the extraction behavior was evaluated

  摘要在本研究中，选择了一种新型的萃取剂，称为六烷基磷酰胺，用于act系元素的分离。六烷基磷酰胺[（NR2）3PO]是具有三个氮亚单元和一个强供体氧原子的化合物。对它们的研究提供了合成多种结构多样的类似物的机会。因此，可以针对特定应用调整萃取剂的所需特性。在本文中，我们讨论了两种此类六烷基磷酰胺（丙基和丁基）的合成，纯化和表征。测量了它们的理化性质，并用U（VI），Th（IV）和Pu（IV）评估了萃取行为。将结果与磷酸三烷基酯如磷酸三正丁酯（TBP）和磷酸三正戊酯（TAP）进行了比较。

  A process for producing a high density polyethylene resin which has a negligible oligomer content while having a melt index ratio of at least 75 by polymerizing ethylene with a minor amount of an aliphatic diene in the presence of a supported organophosphorous modified vanadium-containing catalyst component. Vanadium-containing catalyst components useful with an organoaluminum cocatalyst for polymerizing ethylene vith an aliphatic diene to produce high density resins having not only a low C10-C32 oligomer content (characteristic of high molecular weight polymers having a narrow molecular weight distribution), but, surprisingly, also a melt index ratio desirable for melt blowing applications more characteristic of vanadium catalyzed polymers (which have relatively high oligomer content), are obtained by contacting an inert support material with an organoaluminum compound, an optional halogenating agent, a vanadium compound, and an organophosphorous compound. An aliphatic diene containing at least four carbon atoms in which at least one of the double bonds is in a terminal position is used to copolymerize with ethylene.
