This project is in the general area of analytical and surface                   chemistry and in the subfield of separation science.  The                       thrust of this experimental program is the elaboration of                       linear solvation energy relationships as reliable predictors of                 the effects of solvent on liquid-liquid and liquid-vapor                        separation processes that are critically important in                           analytical gas-liquid chromatography and in separations                         engineering.  Specifically, the fundamental chemical factors                    controlling the partitioning of solutes between gas and liquid                  phases will be studied by head space gas chromatography.                        Solutes and solvents to be examined have been selected to                       reflect a broad spectrum of solvatochromic parameters including                 dipolarity, hydrogen bonding acidity, and basicity and the                      extent of utilization of these solvents in analytical                           chromatography and technologically relevant separations                         processes.  These studies should provide a unifying and                         fundamentally sound bridge between modern partition equilibrium                 theory and commonly used empirical relationships and may                        provide a basis for the rational selection of systems with                      which desired analytical and industrial-scale separations could                 be achieved efficiently and economically.
