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.
