  • Apparatus for preparing a dialkyl carbonate
    Patent number: 7462336
    Abstract: An apparatus for preparing a dialkyl carbonate comprises means for reacting an alkanol, oxygen, carbon monoxide, and a catalyst to form a mixture comprising a dialkyl carbonate, an alkyl chloroformate, hydrochloric acid, water, carbon dioxide, and carbon monoxide; means for separating from the mixture a gaseous fraction comprising carbon monoxide and alkyl chloroformate; and means for removing alkyl chloroformate from the gaseous fraction.
    Type: Grant
    Filed: June 27, 2005
    Date of Patent: December 9, 2008
    Assignee: Sabic Innovative Plastics IP B.V.

  • Method and apparatus for preparing a dialkyl carbonate
    Patent number: 6977308
    Abstract: A method of preparing a dialkyl carbonate includes reacting an alkanol, oxygen, carbon monoxide, and a catalyst to form a mixture that includes a dialkyl carbonate and an alkyl chloroformate. The mixture is separated into a liquid fraction and a gaseous fraction, and alkyl chloroformate is removed from the gaseous fraction. Also described is an apparatus for carrying out the method. The method is particularly useful for preventing corrosion in a cold wash unit that removes further organic impurities from the gaseous fraction.
