  • Deuterated sevoflurane as an inhalational anesthetic
    Patent number: 5789450
    Abstract: Use of D2-sevoflurane is disclosed as an inhalational anesthetic. Deuterated sevoflurane possess all of the desirable qualities of sevoflurane as an anesthetic and is metabolized more slowly thereby reducing potentially toxic inorganic fluoride release. More particularly, the compound fluorodideutero methyl 1,1,1,3,3,3-hexafluoropropyl ether is disclosed as well as a method for synthesis.
    Type: Grant
    Filed: February 15, 1995
    Date of Patent: August 4, 1998
    Assignee: University of Iowa Research Foundation
    Inventors: Max T. Baker, John H. Tinker
  • Process for the synthesis of hexafluoroisopropyl ethers
    Patent number: 5705710
    Abstract: This invention relates to a method of synthesizing 1,1,1,3,3,3-hexafluoroisopropyl ether compounds from the reaction of methoxymalanonitrile with a bromine trifluoride composition.
    Type: Grant
    Filed: January 15, 1997
    Date of Patent: January 6, 1998
    Assignee: University of Iowa Research Foundation
    Inventors: Max T. Baker, John H. Tinker, Jan A. Ruzicka
  • Method of elimination of volatile degradation products of sevoflurane during anesthesia
    Patent number: 5492111
    Abstract: In the process of using sevoflurane as a rapid anesthetic, breakdown of the anesthetic to harmful compound A is slowed if not stopped altogether by cooling the CO.sub.2 scrubber to temperatures that still allow it to work effectively as scrubber but avoid sevoflurane degradation.
    Type: Grant
