| Abstract: | The density, viscosity
and ultrasonic velocity in binary liquid mixtures of morpholin, piperidine with
methanol and pyridine have been determined at different temperatures from
303.15 to 318.15K over the whole composition range. These data have been
utilized to estimate the excess volumes VE,
deviation in viscosity (  ), deviation in adiabatic
compressibility ( ad) and excess
intermolecular free length (LfE) at the above
temperatures. The excess values have been found to be useful in estimating the
strength of the interactions in the liquid mixtures. Analysis of these
parameters indicates that there are intermolecular interactions among
components of the binary mixtures that lead to the possible hydrogen bond
formation (of the type N… H-O and N…H-N) between unlike molecules. |
