The syntheses of the linear tetraamines H2N-(CH2)2-NH-(CH2)n-NH-(CH2)2-NH2 (n = 4 and 5) are described.The protonation of the homologous tetraamines for n = 2, 3, 4, 5, 6 and 8, as well as of N-methylethylenediamine, was investigated using potentiometric and calorimetric measurements.The results obtained are discussed taking into consideration the substituent effect on the basicity of the aminic N-atoms.
