Studies on Synthesis and Characteristics of High Performance Liquid Chromatography Bonded Pase Containing Diaza Crown Ether

Abstract

Abstract: Anew silica gel bonded phase, propyloxy methyl-diaza-1-8-crown-6 silane bonded phase (DN18-C-6), was synthesized via solid-liquid phase three-step-reaction on the surface of prorous silica:the prorous silica gel grafting with γ-gllycidoxypropyltrimethoxysilane; the epoxy-substituted silica reacting by ethylenediamine; the reaction with polyethylene glycol ditosylate in the presence of sodium hydride as catalyst.It possessed good thermal and chemical stabilities and highly separation selectivity for aromatic amine and phenols and the components of nucleic acid.The complexation capacities of DN18-C-6 for sodium and postassium picrate, CuSO₄, AgNO₃, Ni(NO₃)₂ were determined.It showed a good ability to complex with them.

Key words: HPLC, Bonded stationary phase, Diaza crown ether
