New Stationary Phase

Chirasil-β-Dex containing an undecamethylene spacer (C11-Chirasil-Dex) was synthesized and used as chiral stationary phase (CSP) in enantioselective gas chromatography (GC). The versatility of the new stationary phase in the simultaneous enantiomeric separation of a set of N-alkylated barbiturates is demonstrated.

Statistical Approaches

Activity coefficients at infinite dilution have been determined by gas–liquid chromatography for nine hydrocarbons solutes in cyclopentanol, cyclohexanol, cycloheptanol, benzyl alcohol, and n-heptanol at 25 °C. Experimental results for cyclopentane and cyclohexane in cycloalkanols compare favourably with the values obtained by extrapolation to infinite dilution of activity coefficient data calculated from Benson et al.'s static (vapour–liquid equilibrium) measurements. Some characteristics of the solute–solvent interaction in the systems are discussed in light of statistical approaches (thermal and athermal contributions).
