Summary

New experimental data for the isochoric heat capacity for pure DME (dimethyl ether), pure TEG (triethylene glycol) and DME/TEG solutions have been reported in the paper. We also present the description of the experimental setup that realizes method of direct heating in adiabatic calorimeter. The calorimeter has been used for experimental investigation of the two-phase isochoric heat capacity for pure DME, TEG as well as DME/TEG solution at weight fractions of DME 20.8%, 74.7% in temperature range from 152 to 324 ?. The procedure of fitting for the obtained experimental data is reported. The analysis shows that mean uncertainty of measured data does not exceed 0.75%. The temperature and weight fraction dependence for the heat capacity of liquid phase for the mixture of dimethyl ether - triethylene glycol are described in the paper.
