M. Stockhausen et H. Busch, DIELECTRIC-RELAXATION OF BINARY-MIXTURES OF 3 ALCOHOLS WITH DIMETHYLFORMAMIDE, Physics and chemistry of liquids, 32(3), 1996, pp. 183-189
The dielectric spectra of binary liquid mixtures of the following alco
hols with N,N-dimethylformamide (DMFA) have been measured between 5 MH
z and 72 GHz at 20 degrees C:1-Hexanol, 1,2-hexanediol and 1,4-butaned
iol. The analysis of the spectra, which is particularly aimed at infor
mation on hetero-association, gives evidence for the formation of mixe
d aggregations, indicated by a minimum in the 'free' DMFA relaxation c
ontribution at a mixture ratio of about 1:1 for hexanol/DMFA and about
1:2 in case of the dihydric alcohol/DMFA systems.
