Equilibrium Processes in AlkNHCH<sub>2</sub>SO<sub>3</sub>H-NH<sub>2</sub>CH<sub>2</sub>CH<sub>2</sub>OH-H<sub>2</sub>O Solutions
Acid-base interactions in the aminomethanesulfonic ( N -alkylaminomethanesulfonic) acid-monoethanolamine-water (alkyl = methyl, 2-hydroxyethyl, tert -butyl and benzyl) systems in the temperature range of 293-313 K were investigated by pH, redox and conductometric measurements. The ionic and molecular compositions of these solutions and formation constants of ionic pairs and triples were calculated. Relative stability of the ionic associates correlated with lipophilicity (lg P <sub>ow</sub>) and strength (p K <sub>a</sub>) of acids forming them.
