Abstract

IN cases where critical temperatures are unknown they can be calculated from a number of empirical or semi-empirical formulæ1, the simplest but least-accurate being Guldberg's rule. More accurate equations exist for estimating values for hydrocarbons, for example, those of Jatkar and Lakshminarayanan2 and Watson3, but these are unsuitable for use with phenolic and basic organic compounds which occur in coal tar.
