Title (DE) HOCHREINES VINYLENCARBONAT SOWIE EIN VERFAHREN ZUR REINIGUNG VON VINYLENCARBONAT
(EN) HIGH-PURITY VINYLENE CARBONATE AND A METHOD OF PURIFYING VINYLENE CARBONATE
(FR) CARBONATE DE VINYLENE DE GRANDE PURETE ET PROCEDE DE PURIFICATION DE CARBONATE DE VINYLENE
Abstract: front page image
(DE)Die vorliegende Erfindung betrifft die technische Reinigung von Vinylencarbonat (VC) durch eine einfache thermische Behandlung mit organischen Verbindungen, die über amidische Stickstoff- Wasserstoffbindungen verfügen, gefolgt von einer Destillation und einer Schmelzekristallisation. Man erhält so VC höchster Reinheit. Das hochreine Vinylencarbonat kann ohne Stabilisator gelagert und transportiert werden.
(EN)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.
(FR)L'invention concerne du carbonate de vinylène de grande pureté à l'état d'agrégat solide et la purification technique de carbonate de vinylène (VC) par un traitement thermique simple avec des composés organiques qui disposent de composés azote-hydrogène amidiques puis par une distillation et une cristallisation en masse fondue. On obtient ainsi du carbonate de vinylène de grande pureté. Le carbonate de vinylène de grande pureté peut être stocké et transporté sans stabilisant.
