Abstract
The invention relates to a process for making compounds having fatty acid moieties by reacting a fatty acid with a (hydroxyalkyl)amino alkane acid or a (hydroxyalkyl)amine and an aqueous base followed by heating the reaction mixture. The process is particularly useful for the formation of di-fatty acid esters from BES, and tri-fatty acid esters from TES. The reaction parameters can be adjusted to produce useful additional products of the TES-trioleate, including fatty acid amides of mono-, di- and tri-oleoyl-TES.
Claims2
A process for synthesis of compounds containing a fatty acid moiety comprising
- (1) mixing a fatty acid and either a (hydroxyalkyl)amino alkane acid or a (hydroxyalkyl)amine at a temperature between about 80° C. and about 100° C. to form a first mixture;
- (2) adding an aqueous base to the first mixture to form a second mixture;
- (3) heating and mixing the second mixture until homogeneous;
- and
- (4) rapidly heating the second mixture to a temperature between about 130° C. and about 170° C. to remove water and form the compound.
A process for synthesis of compounds containing a fatty acid moiety comprising
- (1) forming a fatty acid slurry having a temperature between about 80° C. and about 100° C.;
- (2) dissolving a (hydroxyalkyl)amino alkane acid or a (hydroxyalkyl)amine in an aqueous base to form a first mixture;
- (3) adding the first mixture formed in step (2) to the fatty acid slurry to form a second mixture;
- (4) heating and mixing the second mixture until homogeneous;
- and
- (5) heating the homogeneous mixture to a temperature between about 130° C. and about 170° C. while removing the water formed by the reaction.
