| Abstract: | Molar excess volumes, VE and molar excess enthalpies, HE, for nitromethane(i) isopropanol or +n-butanol(j) binary mixtures have been measured by dilatometer and microflow calorimeter as a function of composition at 308.15K. The VE data have been analysed in terms of graph-theoretical approach to extract information about the state of isopropanol or n-butanol in pure and mixture states. It has been observed that isopropanol and n-butanol exist as dimer in the pure state and the (i+j) mixtures are characterised by interactions between oxygen and nitrogen atoms of nitromethane (i) with hydrogen and oxygen atoms of alcoholic group of alcohols to form 1:1 molecular complex. The energetics of the mixtures have also been discussed. |
