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. 
Specific heats of the solid-state phases of trimargarin and tristearin
Differential scanning calorimetry is used to obtain specific heats of the α, β′2, β′1 and β phases of trimargarin and tristearin in the temperature range from 190–350 K. Unequal specific heats are
Heats of fusion for some triglycerides by differential scanning calorimetry
Heats of fusion of tristearin, tripalmitin, trimyristin, trilaurin and several standards were determined by the relatively new technique of Differential Scanning Calorimetry. The data obtained on the
Polymorphism of saturated triglycerides: II. 1,3-dipalmito triglycerides
Differential scanning calorimetry was used to examine triglycerides of the 16-N-16 series, whereN is an even-carbon, saturated fatty acid of 2 to 18 carbons in length. The procedures used to obtain
Heats of fusion of glycerides
Triglyceride specific heat determined by differential scanning calorimetry
The specific heats of the three polymorphic forms of trilaurin, trimyristin, tripalmitin and tristearin have been determined by differential scanning calorimetry (DSC). Results from -90 to +100 C for
Physical aging of even saturated monoacid triglycerides
AbstractThe polymorphism and kinetics of phase transformations of triglycerides have been investigated using a polarizing microscope equipped with a variable temperature gradient stage. Differential
Phase behavior of tristearin/trioctanoin mixtures
The thermal behavior of mixtures of two monoacid, saturated triglycerides, tristearin (TS) and trioctanoin (TOC), was investigated with the intent of determining the liquid-solid and solid-solid
Thermal Properties of Tristearin by Adiabatic and Differential Scanning Calorimetry
The thermal behavior of tristearin was studied by adiabatic calorimetry and differential scanning calorimetry (DSC). Specific heat capacities of two polymorphic forms were measured in the adiabatic
