SummaryHeat capacities of the α- and β-forms of trimyristin, tripalmitin, and tristearin, and the β-form of trilaurin were measured. The heats of fusion of the β-forms of these four compounds were determined.The heats of fusion of the α-forms of trimyristin, tripalmitin, and tristearin were calculated from heat content data. Calculations were also made of the heats of transition, α- to β-form.The molal entropy at 298.16° K. was calculated for the β-form of each compound.
