Abstract
The use of ethylene glycol as the solvent in the condensation of carboxylic acid and their derivatives with ethylenediamine or its salts makes it possible to obtain various Δ2-imidazolines in good yields. The ionization constants and the characteristic frequencies of the IR spectra of the synthesized compounds are presented.
