FUSION PROPERTIES OF SOME IONIC QUATERNARY AMMONIUM COMPOUNDS.
Abstract
Enthalpy, entropy and molar volume changes during the fusion process of a wide range of quaternary ammonium compounds are presented. This group of compounds has hitherto been unexplored and is of interest since, as far as melting mechanisms are concerned, it is related to two groups of compounds whose melting phenomena has been studied extensively, the n-paraffins and the alkali metal halides. The data are examined for general trends and comparisons are made with similar data for the paraffins and alkali metal halides. Some regularities in the entropy changes are noted and can be correlated with structural changes within the cation. (Author)
