Orig Pub: Chem. prumysl, 1957, 7, No 8, 402-4o4.
Abstract: A simplified method of analyzinT binary mixtures
of cyclohexanon-cyclohexanol (I in the 0-100%
concentration range has been developed. It is
based on the difference in the dielectric constart
values of the components involved. It consists in
measuring an Increase in the capacity of a conden-
ser filled with anhydrous benzene (II) against that
of a sample of II containing dissolved I. A con-

Abstract: denser of 72 nf capacity (air) is utilized for the
purpose. For a mixture containing 6.25% 1 in 11
the calibrating curve is close to a straight line
for the whole range of I compositions. Results
of the analysis are destorted in the presence of
H 0 If the H20 contained in I,
