“…Complexation equilibria in reversed-phase systems have been studied by Sybilska and co-workers [26,27] as well as other authors [25]. However, modeling of chromatographic process with cyclodextrins as a mobile phase component is still in progress [28].…”

SummaryHigh-performance liquid chromatography and ultraviolet spectroscopy methods were applied to the studies on the influence of temperature on the complexation of 13-cyclodextrin with naphthalene and its derivatives. The strong nonlinearity of Van't Hoff plots suggests, that the retention mechanism of hydrocarbons investigated might be different in high and low temperature region. The total lack of correlation (r = -0.230) between chromatographic data (capacity factors ratio: kPAH/kPAHxCD) and spectrophotometric data (AA) at high temperature (60 ~ as well as a significant correlation (r = 0.922) at subambient temperature (15 ~ suggest, that the inclusion mechanism starts to be important at low temperature region and the predominant mechanism for chromatographic retention is the formation of an inclusion complexes in the mobile phase.

“…Various reversed-phase columns have been cxtensively used to study various molecular interactions such as disubstituted benzene derivatives and cyclodextrins (CDs) (Zukowski et al, 1985), nicotinamide-adenine dinucleotide (NADH) and nicotinamide-adenine dinucleotide phosphate (NADP) with CDs (Uekama et al, 1978a), polycyclic aromatic hydrocarbons, nitrogen heterocyclics and hydroxyl aromatics with BCD (Mohseni and Hurtubise, 1990Hurtubise, , 1991, mandelic acid enantiomers (Debowski et al, 1982) and nitrobenzoic acid isomers with CDs , isomeric alkylbenzenes and CDs (Debowski and Sybilska, 1986).…”

“…[1][2][3] The selective inclusion property has been advantageously utilized in chromatographic separations by capillary electrophoresis (CE) and HPLC. [4][5][6][7][8][9][10][11][12][13][14][15] In CE, cyclodextrins (CDs) are widely used as chiral selectors for enantioseparation or frequently used as electrolyte modifiers to affect the separation and selectivity of analytes with closely related structures. [10][11][12][13][14][15] Chlorophenols are used in a variety of chemical processes as intermediates in the synthesis of dyes, herbicides, pesticides, plastics and drugs.…”
