  • Process for producing vinylene carbonate
    Patent number: 8530676
    Abstract: The present invention relates to the industrial production of vinylene carbonate (VC) by elimination of hydrogen chloride from chloroethylene glycol carbonate (CGC) with tertiary amines in the absence of relatively large amounts of additional solvent.
    Type: Grant
    Filed: May 4, 2006
    Date of Patent: September 10, 2013
    Assignee: SALTIGO GmbH
    Inventors: Reinhard Langer, Anke Beckmann, Paul Wagner, Heinrich Grzinia, Marielouise Schneider, Ulrich Notheis, Lars Rodefeld, Nikolaus Müller
  • High-purity vinylene carbonate and a method of purifying vinylene carbonate
    Patent number: 8071792
    Abstract: 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.
    Type: Grant

    Assignee: Saltigo GmbH
    Inventors: Reinhard Langer, Paul Wagner, Heinrich Grzinia
  • Method of purifying vinylene carbonate
    Patent number: 7999122
    Abstract: 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.
