  • Protonation behavior of 6-deoxy-6-(2-aminoethyl)amino cellulose : a potentiometric titration study
    Fras Zemljič, Lidija ...
    The protonation behavior of 6-deoxy-6-(2-aminoethyl)amino cellulose as a novel soluble aminated derivate of cellulose was studied by means of the potentiometric titration technique. The resulting ... proton binding isotherms exhibit two equivalent steps, which can be described by the standard macroscopic two-pK model, in which the degree of protonation is averaged over all the amine groups. In addition, a microscopic proton binding model was applied, in which the protonation sites are distinguished and the protonation free energy is expanded into an intrinsic term and an electrostatic repulsion between the primary and secondary amine groups. The protonation behavior of 6-deoxy-6-(2-aminoethyl)amino cellulose was compared with a model compound (N-methylethylenediamine).
