  Abstract

Isosteric heats of adsorption of amines on paraffin and polyethyleneglycol were measured by gas chromatography. Values with polyethyleneglycol were significantly higher than those with paraffin due to the N-H…O bonding. The contribution of C-H…O bonding to the isosteric heats of adsorption was negligible. The additional heats of adsorption observed as the sample size increased also increased as the number of amino hydrogen atoms decreased. This tendency was more significant with polyethyleneglycol indicating that strong directing force of amino hydrogen of primary and secondary amines to the surface hinder lateral attractive interaction which could be favored with free orientation.
