  • Working media for refrigeration processes
    Patent number: 8069687
    Abstract: A working medium for refrigeration processes comprising at least one sorbent material and at least one refrigerant, characterized in that the sorbent material contains at least one nonvolatile organic salt which is liquid under standard conditions, or a mixture of organic salts, with the proviso that this is liquid under standard conditions, wherein the salt or the mixture has a thermal stability above 150° C.
    Type: Grant
    Filed: May 24, 2006
    Date of Patent: December 6, 2011
    Assignee: Evonik Degussa GmbH
    Inventors: Carsten Jork, Matthias Seiler, Bernd Weyershausen

  • Recycling of ionic liquids produced in extractive distillation
    Patent number: 7485208
    Abstract: Process for working up a bottom stream wherein high boilers and ionic liquid from an extractive rectification in which the ionic liquid is used as entrainer. The process includes feeding the bottom stream to an evaporation stage which is operated at a pressure of less than 500 mbar or to a stripper which is operated through use of inert gas or steam, and the major part of the high boiler present is separated off in vapor form from the ionic liquid.
    Type: Grant

    Date of Patent: February 3, 2009
    Assignee: BASF Aktiengesellschart
    Inventors: York Alexander Beste, Hartmut Schoenmakers, Wolfgang Arlt, Matthias Seiler, Carsten Jork
  • Ionic liquids as selective additives for separation of close-boiling or azeotropic mixtures
    Patent number: 7435318
    Abstract: The invention relates to a process for separating close-boiling, homo- and heteroazeotropic mixtures by using ionic liquids. Due to the selectivity and unusual combination of properties of the ionic liquids the process is superior to conventional extractive rectification from the point of view of costs and energy.
