Thermokinetic Research of Consecutive Quaternizations

Abstract

Abstract: The consecutive quaternization between N, N, N', N'-tetramethyl-1, 3-propylenediamine and bromobutane in DMFand DMSOat 25.0℃, 35. 0℃ and 45.℃was studies with thermokinetic method. Rate constants of two steps were calculated, and activation energies and activation free-energies were obtained. The influences of temperature and solvent on the reaction kinetics have been discussed, which is considered to be important for the elucidation of the formation mechnism and the choice of synthetic conditions of ionene polymers.

Key words: Quaternization, Consecutive reaction, Thermokinetics, Calorimetry
