    • Process for the destillative purification of fluoroethylene carbonate Crude fluoroethylene carbonate obtained by the fluorination of ethylene carbonate and elemental fluorine containing not more than 5 % by weight of HF is purified by at least two subsequent distillation steps. The bulk of HF can be removed, if desired,in a preliminary HF removal step, e.g. by stripping,before performing the distillation. Further,if desired, a second HF removal step can be performed by contacting the crude mixture or the distillate obtained after the first distillation step with an adsorbent for HF, e.g. silica gel. The distillation can be performed batch wise. It is preferred to perform it continuously. It yields purified fluoroethylene carbonate with an HF content of equal to or less than 30 ppm. The purified fluoroethylene carbonate can be applied as solvent additive for lithium ion batteries.
    • 氟代碳酸亚乙酯的游离纯化方法通过氟化碳酸亚乙酯和含有不超过5重量%HF的元素氟获得的粗氟代碳酸亚乙酯通过至少两个随后的蒸馏步骤纯化。 如果需要,可以在初步HF去除步骤中除去大部分HF。 通过汽提,然后进行蒸馏。 此外,如果需要,可以通过使在第一蒸馏步骤后获得的粗混合物或蒸馏物与HF的吸附剂接触来进行第二HF去除步骤,例如。 硅胶。 蒸馏可以分批进行。 优选连续执行。 产生HF含量等于或小于30ppm的纯化氟代碳酸亚乙酯。 纯化的碳酸亚乙酯可用作锂离子电池的溶剂添加剂。

    • The invention provides a container containing a fluorinated organic carbonate and a gas atmosphere which contains cover gas selected from the group consisting of a noble gas, e.g., argon, xenon, a gaseous fluorinated aliphatic carbon which is heavier than air and does not interfere with the fluorinated organic compound, and SF 6 , or any mixture thereof,. Fluorinated organic carbonates are highly suitable as solvents or additives for solvent in Li ion batteries and consequently, must be kept in a very pure state even during expanded times of storage. The argon or xenon gas atmosphere prevents the intrusion of air or moisture even if the container is opened and the liquid handled in an environment of common air. The invention also provides for a method of storing fluorinated organic carbonates in a safe manner.
    • 本发明提供了含有氟化有机碳酸酯和气体气氛的容器,该气体气体含有选自惰性气体例如氩气,氙气,比空气重的气态氟化脂族碳并且不干扰 氟化有机化合物和SF 6,或其任何混合物。 氟化有机碳酸酯非常适合作为Li离子电池中溶剂的溶剂或添加剂,因此,即使在扩展储存期间,也必须保持非常纯的状态。 氩气或氙气气体即使打开容器并且在普通空气环境中处理液体也能防止空气或水分侵入。 本发明还提供了一种以安全的方式储存氟化有机碳酸酯的方法。
