  • Synthesis of severely sterically hindered secondary aminoether alcohols from a ketene and/or carboxylic acid halide and/or carboxylic acid anhydride
    Patent number: 7538251
    Abstract: Severely sterically hindered secondary aminoether alcohols are prepared by a process comprising reacting a ketene with sulfuric acid to produce an anhydride which is then reacted with, to cleave the ring of, a dioxane to yield a cleavage product which is then aminated using an amine, followed by hydrolysis with a base to yield the desired severely sterically hindered secondary aminoether alcohol.
    Type: Grant
    Filed: February 1, 2005
    Date of Patent: May 26, 2009
    Assignee: ExxonMobil Research and Engineering Company
    Inventors: Michael Siskin, Alan Roy Katritzky, Kostyantyn Mykolayevich Kirichenko, Adeana Richelle Bishop, Christine Nicole Elia
  • Synthesis of sterically hindered secondary aminoether alcohols
    Patent number: 7524990
    Abstract: Severely sterically hindered secondary aminoether alcohols are prepared by reacting organic carboxylic, organic carboxylic acid halides, acid anhydrides or a ketene with an alkyl, alkaryl or alkylhalo sulfonate to yield a sulfonic-carboxylic anhydride compound which is then reacted with a dioxane to cleave the ring of the dioxane, yielding a cleavage product which cleavage product is then aminated with an alkylamine and hydrolyzed with base to yield the severely sterically hindered secondary aminoether alcohol.
    Type: Grant
    Filed: February 1, 2005
    Date of Patent: April 28, 2009
    Assignee: ExxonMobil Research and Engineering Company
    Inventors: Michael Siskin, Alan Roy Katritzky, Kostyantyn Mykolayevich Kirichenko, Adeana Richelle Bishop, Christine Nicole Elia
  • Synthesis of sterically hindered secondary aminoether alcohols
    Patent number: 7429680
    Abstract: Severely sterically hindered secondary aminoether alcohols are prepared by reacting an organic carboxylic acid or alkali metal salt of an organic carboxylic acid with a sulfonyl halide, a sulfuryl halide, a mixed sulfuryl ester halide or a mixed sulfuryl amide halide to yield a sulfonic-carboxylic anhydride compound which is then reacted with a dioxane to cleave the ring of the dioxane, yielding a cleavage product which cleavage product is then aminated with an alkylamine and hydrolyzed with base to yield the severely sterically hindered secondary aminoether alcohol.

    Date of Patent: September 30, 2008
    Assignee: Exxonmobil Research and Engineering Company
    Inventors: Michael Siskin, Alan Roy Katritzky, Kostyantyn Mykolayevich Kirichenko
  • Synthesis of sterically hindered secondary aminoether alcohols from acid anhydride and/or acid halide and sulfur trioxide
    Patent number: 7351865
    Abstract: Severely sterically hindered secondary aminoether alcohols are prepared by reacting acid anhydrides or organic carboxylic acid halides with SO3 to yield a sulfonic carboxylic anhydride compound which is then reacted with a dioxane to cleave the ring of the dioxane yielding a cleavage product which is then aminated with an alkylamine and hydrolyzed with a base to yield the severely sterically hindered secondary aminoether alcohol.
