The dielectric relaxation of mixtures of water and primary alcohol

摘要: Dielectric measurements over a microwave frequency range 10 MHz–15 GHz were carried out by the use of new time domain reflectometry equipment on mixtures water with five primary alcohols, viz., methanol, ethanol, and n‐propanol in concentration 0≤x≤1 n‐butanol amyl alcohol 0≤x≤0.5 at room temperature; x being mole fraction water. The systems two alcohols low molecular weight are characterized single relaxation distribution parameter unity or near to it. reorientation as well these is cooperative process involving large number molecules hydrogen‐bond linkages (O–H⋅⋅⋅O). behavior methyl ethyl due structure hydrogen‐bonded network microscopically homogeneous. Microscopic heterogeneity occurs higher alcohols.
