Abstract:
The viscosity of titanium (III) soaps of higher fatty acids
in mixed organic solvents has been measured over a
temperature range of 35-50°C. The critical micelle
concentration is found to be independent of temperature, but
decrease with increasing chain length of the soap. The
equation of Vand and Moulik are applicable above C.M.C of
the soaps the parameters of the equations have been
evaluated. The effect of soap concentration on viscosity of
soap solution has also been discussed in the light of
Eyring’s equation and the thermodynamic parameters
DH*,
DS* and
DG* have been calculated.
Keywords:
Titanium, Fatty acids, Viscosity.
