Abstract

Heat capacities for 1,2-dimethoxybenzene, 2,5,8,11-triethylene glycol dimethyl ether, N-ethyl-2-pyrrolidone, isopentyl acetate, 2-ethylhexanal, toluene, 1-phenylethanol, propyl acetate, octyl acetate, dimethyl sulfoxide, diethyl phthalate, and diethyl carbonate were measured with the “three-step” method using a Tian−Calvet batch calorimeter. The measurements of saturated liquid heat capacity have an approximate uncertainty of ±0.5% and cover a temperature range between 310 K and 420 K. Furthermore, the experimental results were compared with three group contribution methods for liquid heat capacities.
