  • Purification of tertiary formamide contaminated with tertiary acetamide
    Patent number: 8981079
    Abstract: A chlorinating agent such as a chloroiminium species is used to remove or neutralize tertiary acetamide present as a contaminant in a tertiary formamide solvent. Tertiary formamide solvent purified or treated in this manner can be used as a reaction vehicle for the chlorination of sucrose-6-acylates, thereby improving the yields of the desired sucralose-6-acylate (an intermediate in the production of sucralose).
    Type: Grant
    Filed: June 18, 2010
    Date of Patent: March 17, 2015
    Assignee: Tate & Lyle Technology Limited
    Inventors: James Edwin Wiley, Jr., Mohamad R. Jaber
  • Chlorination of sucrose-6-esters
    Patent number: 8530643
    Abstract: A method for the chlorination of a sucrose-6-acylate to produce a 4,1?,6?-trichloro-4,1?,6?-trideoxy-galactosucrose-?-acylate wherein said method comprises: (i) reacting the sucrose-6-acylate with a chlorinating agent in a reaction vehicle comprising a tertiary amide in order to chlorinate the 4, V and 6? positions of the sucrose-6-acylate; and (ii) quenching the product stream of (i) to produce a 4,1?,6?-trichloro-4,1?,6?-trideoxy-galactosucrose-6-acylate; wherein before said quenching, a portion of the tertiary amide is removed.
