Acyl migration solid phase isomerization of 1,2‐diglycerides to 1,3‐isomers

Abstract

In mixtures of 1,2- and 1,3-diglycerides stored some degrees below their melting points, a rather rapid isomerization of almost all the 1,2- diglycerides to the 1,3-isomers occurred. This solid-phase isomerization leads to a substantial increase in the yield of saturated and unsaturated mono- and mixed-acid 1,3-diglycerides.
