High-frequency conductivity of mixtures of water with methanol, ethanol, and propanol

High-frequency (HF) electric conductivity (EC) of mixtures of water with methanol, ethanol, and propanol was analyzed. The limiting HF conductivity decreased at increasing alcohol content in the mixture and passed through a maximum at 2455 MHz. The rate of HF heating of the aqueous solutions of alcohols was determined using a Discover Bench Mate microwave system at a frequency of 2455 MHz. The maximum rate of HF heating was observed in solutions with the highest HF conductivity.
