Abstract

The van der Waals volume and enthalpy of alkanes and alkylalcohols were calculated using the CAChe-MOPAC-BlogP program. These values were correlated with van der Waals volumes calculated by Bondi′s method and enthalpies measured using a capillary column gas chromatograph. Further, the boiling points were analyzed by using their capacity ratios and physicochemical properties. The proposed boiling point of the alkanes and alkylalcohols are presented.
