Kn. Mehrotra et M. Anis, SPEED OF SOUND MEASUREMENTS ON ZIRCONYL SOAP SOLUTIONS IN XYLENE PLUSMETHANOL, Journal of chemical and engineering data, 41(3), 1996, pp. 394-396
The speed of sound in solutions of zirconyl soaps (caproate, caprylate
, and caprate) in xylene + methanol (volume ratio of 4:1) increases wi
th increasing concentration and chain length of the soap. The isentrop
ic compressibility (k(s)), apparent molar compressibility (phi(k)), an
d apparent molar volume (phi(v)) were evaluated, and the results were
explained in terms of solute-solvent interactions. It is concluded tha
t the soap molecules do not aggregate appreciably below the critical m
icellar concentration.
