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 Ris hydrogen, alkyl, aryl or (CH)&#x2014;COOR; wherein Ris wherein R, Rand Rare hydrogen, or &#x2014;(O)C&#x2014;(CH)&#x2014;CH&#x2550;CH&#x2014;Ror &#x2014;(CHCHO)H or mixtures thereof; wherein m is 1 to 9; and wherein n is 1 to 100.

Glycitan esters of unsaturated fatty acids and their preparation

An alkenyl glycoside is prepared by reacting a metathesis-derived unsaturated fatty alcohol containing 10 to 30 carbon atoms with either (1) a reducible monosaccharide or composition hydrolyzable to a reducible monosaccharide, or (2) a hydrocarbyl glycoside produced by reacting an alcohol containing up to 6 carbon atoms with a reducible monosaccharide or composition hydrolyzable to a reducible monosaccharide. Each of these reactions is performed in the presence of an acid catalyst and under conditions sufficient to form the alkenyl glycoside or hydrocarbyl glycoside. The preferred alkenyl glycosides are 9-decen-1-yl glycoside; 9-dodecen-1-yl glycoside; 9-tridecen-1-yl glycoside; 9-pentadecen-1-yl glycoside; 9-octadecen-yl glycoside; or 9-octadecen-1,18-diyl glycoside.
