All experimental measurements were carried out by using a PSL Systemtechnik instrument in which transient hot-wire method was employed to measure transport properties, λ and αD. All obtained data were correlated by using empirical linear temperature function with a very good correlation coefficient, better than R2 = 0.99. Among the solvents tested in this paper, except for TEA, the thermal diffusivity decreased by increasing temperature and also except for TEA and ETG, thermal conductivity decreased with temperature.}, keywords = {Thermal Property,Alkanolamine,Physical Solvents,Chemical Solvents,Heat Capacity,Thermal conductivity,Thermal Diffusivity}, url = {https://www.ijche.com/article_11673.html}, eprint = {https://www.ijche.com/article_11673_801984c73cf2ccef5e125d465b421f3f.pdf} }
