Hello Ken, fatty acids are possible to esterify with an acid catalyst. The formed water has to be drawn off, so it is always nice to start with a low water content. Performed correctly, the esterification will produce 90-95% esters. Usually these kinds of reactions are performed twice for a good conversion grade.
