Abstract
Official abstract text for this publication.
A method is disclosed for making an unsaturated glycitan ester by reacting intramolecular condensates of glycitols having four or more carbons with a metathesis-derived unsaturated fatty acid in the presence of an alkaline catalyst and under conditions sufficient to form the aforesaid unsaturated glycitan fatty ester. A composition is also disclosed comprising a compound of the following structure: wherein R 1 is hydrogen, alkyl, aryl or (CH 2 ) 1-9 —COOR 5 ; wherein R 5 is wherein R 2 , R 3 and R 4 are hydrogen, or —(O)C—(CH 2 ) m —CH═CH—R 1 or —(CH 2 CH 2 O) n H or mixtures thereof; wherein m is 1 to 9; and wherein n is 1 to 100.
First claim
Opening claim text (preview).
We claim: 1. A method for preparing a glycitan ester of an unsaturated fatty acid comprising: providing an intramolecular condensate of a glycitol, the intramolecular condensate having four or more carbon atoms; reacting the intramolecular condensate with an unsaturated fatty acid, or an ester thereof, to form the glycitan ester of the unsaturated fatty acid, or the ester thereof, wherein the unsaturated fatty acid, or the ester thereof, is selected from the group consisting o…
