乙醇钽(V) 制备方法及用途

制备方法

制备用仪器和试剂事先都需经干燥和除水处理,并避免潮气的进入。 10g五氯化钽悬浮在200mL无水苯中,慢慢加入25mL无水乙醇,发生猛烈的反应并产生氯化氢气体。待猛烈的反应平息后,通入过量的氨气,待析出氯化铵沉淀后,滤出。滤液在减压下蒸发,将剩余物进行真空蒸馏,收集145~147℃/13.34Pa产品约11g。

    Where risk assessment shows air-purifying respirators are appropriate use a full-face respirator
    with multi-purpose combination (US) or type ABEK (EN 14387) respirator cartridges as a backup
    to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air
    respirator. Use respirators and components tested and approved under appropriate government
