Abstract
At 30 degrees C the complex (dielectric) permittivity of the system morpholine/n-butanol has been measured as a function of frequency nu (5*104 Hz10 Hz) and mole fraction x (0<or=x<or=1). Within the frequency range under consideration all liquids show a relaxation region with an underlying unsymmetrical distribution of relaxation times. The static permittivity, the characteristic dielectric relaxation time, and the width of the relaxation time distribution function are discussed. Other than what is expected on the grounds of recent permittivity measurements at 100 kHz no unusual properties are found for the binary mixtures.
