EFFECTS OF DILUTION OF POLY(ETHYLVINYLBENZENE DIVINYLBENZENE) ADSORBENT ON THE ADSORPTION OF ALIPHATIC, ALICYCLIC, AND AROMATIC HYDROCARBON ADSORBATES FROM EFFECTIVE ZERO TO FINITE SURFACE COVERAGE

The chromatographic measurement and systematic interpretation of the solid/gas partition coefficients K//S and related thermodynamic properties of a number of hydrocarbon adsorbates (n-pentane through n-octane, cyclohexane, methylcyclohexane, benzene, dichloromethane, chloroform, carbon tetrachloride, tetrahydrodrofuran, thiophene, and acetone) at effective zero surface coverage with a 1:10 admixture of the title adsorbent-inert diluent from 393 to 443 K are reported. Despite a difference of an order of magnitude in the surface areas of bulk and admixed packings, the adsorbate relative retentions were in good agreement with those found in previous work with neat Porapak Q.
