Abstract:The polymorphism of 1,3-dipalmitin, 1.2-dipalmitoyl-sn-glycerol, 1.2-dipalmitoyl-ruc-glycerol has been examined by X-ray diffraction, IR spectroscopy and Raman spectroscopy and differential scanning calorimetry. The respective spectra and thermographs are presented for these polymorphs. Optically active 1,2-diglycerides exhibit very different thermal behaviour from the optically inactive 1,2-diglycerides. A novel HPLC system was devised for the separation of the diglycerides.
