  摘要：

  AbstractThe synthesis of symmetrical and asymmetrical palmito‐ and stearo‐elaidic triglycerides (PEP, SES, EPP, PEE, ESS, and SEE, in which P=palmitic, S=stearic, and E=elaidic acid) was undertaken to investigate their polymorphism. The chemical pathways and the purification steps, including crystallization and adsorption chromatography, are described. The different chromatographic analyses (gas‐liquid chromatography: carbon number profile and fatty acid methyl ester profile, and high‐performance liquid chromatography) revealed that the purity of the synthesized products was superior to 99% except for SES (>96%). The thermal behavior, as well as the polymorphism of these triglycerides, has been investigated by means of differential scanning calorimetry and powder X‐ray diffraction spectroscopy at variable temperatures. The six compounds crystallize according to a double chainlength packing. The most stable polymorphic form of palmito‐elaidic triglycerides belongs to the β′ variety, whereas the stearo‐elaidic triglycerides are β stable.
