Mobility of molecules of liquid diols in the temperature range of 303–318 K

The self-diffusion coefficients of diols (ethylene glycol (EG), 1,2- and 1,3-propanediols (PD), and 1,4-butanediol (BD)) are measured using the spin echo approach on protons in the temperature range of 303–318 K. The activation energies of self-diffusion are calculated and compared to the activation...

Description
Summary:The self-diffusion coefficients of diols (ethylene glycol (EG), 1,2- and 1,3-propanediols (PD), and 1,4-butanediol (BD)) are measured using the spin echo approach on protons in the temperature range of 303–318 K. The activation energies of self-diffusion are calculated and compared to the activation energies for viscous flow and dipole relaxation in these systems. A conclusion is reached as to the correlation of rotational and translational movements in liquid diols, due to the presence of a spatial network of hydrogen bonds in these solvents.
