制备方法与用途

制备方法

1. 在聚乙烯制的反应器（约250毫升）中加入约10克四氯化钒，并放入包裹着聚四氟乙烯的磁子。反应器中装有聚乙烯制的冷凝器。随后，加入20克一氟三氯甲烷CCl3F，并将反应器冷却至-78℃。操作过程中应快速通入氮气流，以防止湿气进入反应系统。在搅拌下使25～30毫升无水氟化氢在容器中冷凝。添加完毕后，缓缓提高容器的温度。不到3小时使温度降至室温。反应结束后，过剩的氟化氢或溶剂在容器加热至30～35℃时即会蒸发除去，而纯四氟化钒将存留其中。

2. 在镍舟中加入约5克钒，并置于直径为2.5厘米的镍制反应器中。安装并固定一排玻璃捕集器。加热反应器至150～200℃, 并通入用氮气稀释的氟气达2小时之久。然后将反应器密封，在干燥箱内打开，则位于反应器出口附近，生成暗绿色的四氯化钒固体。

• Interaction between uranium pentafluoride and the pentafluorides of vanadium, arsenic, niobium, tantalum, and bismuth, and the tetrafluoride of sulphur

  日期：——

  The interaction of UF5 with SF4, SF4O, and some Lewis-acid pentafluorides of various strengths has been studied. In anhydrous HF solutions, SF4 was shown to yield an adduct of composition 3UF5·SF4 in which both ionic and fluorine-bridged species are present. The pentafluorides of arsenic, tantalum, and niobium combine with UF5 to give adducts of composition 1.5 UF5·AsF5, UF5·2TaF5, and UF5·2NbF5, respectively

  已经研究了UF 5与SF 4，SF 4 O和一些不同强度的路易斯酸五氟化物的相互作用。在无水HF溶液中，显示SF 4可以生成组成3UF 5 ·SF 4的加合物，其中同时存在离子和氟桥联物质。砷，钽和铌的五氟化物与UF 5结合，分别得到组成为1.5 UF 5 ·AsF 5，UF 5 ·2TaF 5和UF 5 ·2NbF 5的加合物。砷衍生物只有在AsF 5的压力下才能在室温下稳定，而钽和铌加合物在较高温度下分解，分别形成UF 5 ·TaF 5和UF 5 ·NbF 5。UF 5的五氟化物加合物的振动光谱研究表明，它们由共价的氟桥连物种组成。五氟化铀在室温下通过VF 5和BiF 5在无水HF中进行氟化。

  Shock‐sensitive and highly explosive V(N3)4 was prepared from VF4 and Me3SiN3 by fluoride–azide exchange. Salts of the [V(N3)6]2− anion (see picture) were obtained by treatment of the neutral tetraazide with ionic azides. Vanadium(V) azide, the only binary vanadium(V) compound known apart from VF5, VF6−, and V2O5, was successfully prepared from the VF6− anion.
