Abstract : Absolute entropies of compounds in homologous series of hydrocarbons, ketones, and alcohols were found to be directly related to the logarithm of the retention volumes obtained from gas-liquid chromatographic measurements. Different liquid substrates and column temperatures have been employed in the collection of retention data. The retention volume method can be employed as a fast and relatively inexpensive way of predicting absolute entropies of organic compounds. (Author)
