Changes in the mean least intermolecular distances in a solution of 2-methy
l-2-propanol in cyclohexane with increasing concentration of the former wer
e found to be non-linear. Both in the range of low (0.005-0.04 molar fracti
on) and high (0.45-0.75 molar fraction) concentrations of the solutions stu
died local maxima of the mean least intermolecular distance were observed.
In the range from 0.8 to 1 molar fraction the value of this parameter remai
ned constant. Results obtained in this work prove the absence of the specif
ic structural properties of a low concentration alcohol solution observed i
n other solvents. The occurrence of the local maxima proves that cyclohexan
e is a non-active solvent. Owing to this the molecules of the solute and th
e solvent assume positions ensuring homogeneity of the solvents.
