Abstract

The retention and selectivity behavior of some aromatic hydrocarbons and alkylbenzenes on phenyl‐ or phenylpropyl‐modified glasses have been studied by high performance liquid chromatography. From elemental analysis data for carbon, the maximum number of accessible phenyl or phenylpropyl surface groups per 100 Å^2^ of glass (mean pore diameter, 157 Å; specific surface area, 213 m^2^/g) in the phenyl and phenylpropyl modified glasses were calculated to be 1.93 and 1.97, respectively. Using 60:40 methanol‐water mixtures as eluents, the aromatic hydrocarbons or alkylbenzenes were separated on the glasses studied, but with different degrees of resolution.
