| Abstract: | The protonation equilibria in aqueous solution of α,ω-thiadiamines of general formula (R)(R′)N(CH2)n,S(CH2)mNH2 (R,R′= CH3 or H) have been investigated potentiometrically and calorimetrically at 25° C in 0.5 mole dm?3 KNO3 solution. The enthalpy and entropy changes are discussed in terms of intrinsic proton affinities and solvation effects. |
