摘要： The present invention relates to the industrial purification of vinylene carbonate (VC).It was found that it is advantageous to subject the VC to be purified, before the purifying distillation, to a simple thermal treatment with organic compounds which have amidic nitrogen-hydrogen bonds.
摘要翻译： 本发明涉及碳酸亚乙烯酯（VC）的工业纯化。 已经发现，在纯化蒸馏之前使VC纯化得到具有酰胺型氮 - 氢键的有机化合物的简单热处理是有利的。

摘要： The present invention relates to the technical purification of vinylene carbonate (VC) by means of a simple thermal treatment with organic compounds which possess amidic nitrogen-hydrogen bonds, followed by a distillation and a melt crystallization. In this way VC of ultra-high purity is obtained. The high-purity vinylene carbonate can be stored and transported without stabilizer.
摘要翻译： 本发明涉及通过简单的热处理与具有酰胺氮 - 氢键的有机化合物进行蒸馏和熔融结晶的碳酸亚乙烯酯（VC）的技术纯化。 以这种方式获得超高纯度的VC。 高纯度碳酸亚乙烯酯可以在没有稳定剂的情况下储存和运输。
