Abstract

on exchanged forms of three high silica zeolites, *BEA (beta), EUO (EU-I), TON (NU-1), were studied for their potential to separate isomers of industrial interest. This was approached by using them as stationary phases in high performance liquid chromatography (HPLC). Methods of pelleting are discussed. Successful separations of isomers were observed for: dimethylbenzenes, diethylbenzenes, dichlorobenzenes, dinitrobenzenes, dinitrotoluenes, chlorotoluenes, nitrobenzaldehydes, hydroxytoluenes, chlorophenols, nitrophenols, chloroanilines and nitroanilines. The influences of zeolite structure, Si/Al ratio and cation contents are considered.
