Abstract
The heat capacities and thermal diffusivities of n-alkanoic acid methyl esters CnH2nâ1O2CH3 with n from 6 to 12 have been measured. The heat capacities have been measured in the temperature range from 303.15â¯K to 373.15â¯K; the measurements of thermal diffusivity have been carried out for a given methyl ester from 303.15â¯K to the temperature at which a noticeable evaporation of the ester took place. The temperature dependencies of the heat capacities and thermal diffusivities have been approximated by a third-order and a first-order polynomial, respectively. It has been shown that the dependence of the molar heat capacity on n (nâ¯=â¯1-14) at a temperature of 298.15â¯K is close to linear.
