Prediction of Absolute Entropies from Gas Chromatographic Retention Data

摘要

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)
