摘要:

Earlier, phase transitions of triterpene fatty acid esters were studied for a few new triterpenes in this lab. In the present investigation, synthesis of axial and equatorial fatty acid esters of a triterpene were synthesised and their liquid crystal transition temperatures were determined using a polarising microscope. The effect of equatorial and axial orientation of the ester grouping on phase transitions was highlighted.
