Conclusions
-
1.
Solutions of partly protonated higher primary amines (≥C6) contain mixed micelles that catalyze the hydrolysis of the ester bonds at the phosphorus through the general basic mechanism. The catalytic rate constants in the micellar phase are only very slightly dependent on the length of the hydrocarbon chain in the amine.
-
2.
At low concentrations, the higher amines form premicellar associates, for which the catalytic activity increases with increasing length of the radical.
