Abstract
Values of molar retraction for every studied mixtures show linear plot s versus molar fractions of triglyceride. Values of molar volume show this behaviour, but only for tributyrin-butanol or tricaprylin-butanol miscellas However, in triburyrin-ethanol mixtures, volume contraction s have been found, whereas triacetin-butanol and tributyrin-hexanol sn ow volume expansions. These facts are related to the mode of being str uctured of the alcohol and triglyceride molecules in mixtures. A linea r relationship between molar volume and temperature have been found, a nd also a linear dependence between the coefficient of thermal expansi on at constant pressure and the molar fraction of triglyceride.
