The Study of Resin Column Chromatographic Separation about Amines

Abstract

Abstract:

The static adsorptions of aniline, N-methylaniline and N, N-dimethylaniline onto ADS-17 in nonpolar solvent and water were studied. The results show that in nonpolar solvent, the adsorption sequence was aniline, N-methylaniline and N, N-dimethylaniiine. The adsorption mechanism relates to the form of hydrogen-bonding. But in water the adsorption sequence was opposite. This appreciates to hydrophobic interaction. In water those three amines could be isolated by dynamic chromatographic separation with the polycarboxylic ester sorbent. The results indicate the feasibility of chromatographic separation of alkaloid in normal press using special resin.

Key words: sorbent, amine, chromatographic separation
