Dependence of Permeability of SPEV Cell Membranes for Molecules of Ethylene Glycol and 1,2-Butane Diol on Temperature
Keywords:permeability coefficients, activation energies, SPEV cells, volumometry, ethylene glycol, 1, 2-butane diol
Using the method of volumometry the permeability coefficients for SPEV cell membranes of ethylene glycol (EG) and 1,2-butane diol (1,2-BD) at temperatures of 35, 18 and 7Â°C have been determined. The calculated within the range of temperatures of 35â€“7Â°C values of permeability activation energy for molecules of EG and 1,2-BD make 45.07 and 55.35 kJ/mol, correspondingly. The differences in membrane permeability for EG and 1,2-BD molecules are the most manifested at 35Â°C and are absent at 7Â°C.
