Abstract: p-t-Butyl-calixarene bonded silica stationary phase(CBS) for high performance liquid chromatography was prepared via condensation reaction on the surface of solid .The stationary phase was characterized by means of elemental analysis and FTIR. The chromatographic performance of CBS was studied by using disubstituted benzenes as the solutes and methanol-water or methanol-buffer as the mobile phases, and compared with that obtained on CPS and ODS. The results show that the chromrtographic process can proceed in various retention mechanism, such as π-π, hydrogen-bonding, charge-transfer and inclusion complexation, besides hydrophobic interaction.

Key words: Continuous reaction on the surface of solid, p-t-Butyl-calix[8]arene bonded silica stationary phase, HPLC
