Spectroscopic Analysis of Chromium Soaps
The spectroscopic characteristics of chromium soaps (butyrate and caprylate) in solid state were investigated by IR, X-ray diffraction and thermal measurements. The IR results reveal that the fatty acids exist in dimeric state through hydrogen bonding and soaps possess partial ionic character. The X-ray diffraction measurements were used to calculate the long spacings and the results confirm the double layer structure of chromium soaps. The decomposition reaction was found kinetically of zero order with energy of activation .275 and .180 kcal mol-1 for butyrate and caprylate, respectively.
Conductometric Studies on Manganese Soap Solutions
The conductometric studies of the solution of manganese butyrate and caprylate in a mixture of 50% Benzene and 50% Methanol (v/v) were employed to determine the specific conductance, limiting molar conductance at infinite dilution, degree of dissociation, dissociation constant and CMC. The values of critical micelles concentration decreases with increasing chain length of fatty acid component. The result show that the soaps behaves as a weak electrolytes below the CMC. The thermodynamic parameters for both dissociation and association processes are evaluated.
