Polarizability of coal liquefaction product distillates: Insight into intermolecular forces

Abstract

A purpose of this investigation is to gain insight into the intermolecular forces present in coal liquefaction products. The mid-boiling point of distillates from coal liquefaction products reflects the intermolecular forces present. The mid-boiling point of distillates from H-Coal and Wilsonville products is a linear function of their average molar volume and average molar polarizability, which are directly related to van der Waals forces. The results presented here support, but do not prove, the conclusion that van der Waals forces are the dominant intermolecular forces in the H-Coal and Wilsonville distillates.
