Conclusions
-
1.
A study was made of the interaction of aminothiols (AT) with H2O2, as affected by the acidity of the medium, the temperature, the ionic strength of the solution, and the structure of the AT; the reacting particles were the thiolate anion and the molecular form of hydrogen peroxide.
-
2.
The reaction was promoted by hydrogen bonding between the OH− group splitting off and the amino group of the AT, and by the attraction between the OH− group and the positively charged end of the zwitterion form of the AT.
-
3.
Intermolecular hydrogen bonding and the electrostatic effect introduced equal contributions to the activation of the reaction.
