LIQUID VOLUME AT NORMAL BOILING-POINT

The atomic and structural contributions proposed by Schroeder (Parting ton, 1949) for estimating the molar volume at the normal boiling point have been revised to improve the accuracy. Extensive testing with dat a for 163 organic liquids gave average and maximum absolute deviations of 1.4% and 7.2%, respectively. The corresponding average absolute de viations for the Schroeder (Partington, 1949), LeBas (1915) the Tyn an d Calus (1975) methods are found to be 3.6%, 2.9% and 2.5%, respective ly.
