Sorption of aldehydes on methacrylate-styrene gels with primary amine functional groups

A. Bukowska W. Bukowski D. Machowski

Abstract

Low crosslinked glycidyl methacrylate (GMA) terpolymers with a functionalization degree of 1.4 mmol/g have been chemically modified with ethylenediamine (EDA), diethylenetri-amine (DETA), or tris(2-aminoethyl) amine (TAEA) to obtain reactive gels with polyamine functional groups (Figs. 3-5). The varying swelling properties of the obtained resins in selected organic solvents -THF, methylene chloride, methanol and the mixture of CH2C12:CH3OH (1:1, V:V) were examined (Fig. 6). The sorption capacity of the aromatic aldehydes - salicylaldehyde, 3,5-di-ferf-butylsalicylaldehyde, 3,5-dichlorosalicylaldehyde (Figs. 7-16), benzaldehyde and 2-ethoxybenzaldehyde in these solvents determined (Table 1). The studies confirm that the rate of chemical bonding of the modified resins with aldehydes does not depend exclusively on the chemical structure of the aldehyde which is responsible for their affinity to primary amine groups and the amount of NH2 groups present in the resin (Figs. 1,2), but also on various factors among which are the chemical nature of the solvent and the solvent-resin interaction, on which the degree of resin swelling depends.
