Abstract
The influence of the detergentless water/oil microemulsion formed in t he n-hexane-water-2-propanol system on the kinetics of the hydrolysis of di(p-nitrophenyl) methyrphosphonate under the conditions of general base catalysis by primary, secondary, and tertiary aliphatic amines w as investigated. The leveling of the catalytic rate constants and basi cities of the amines was found for this reaction in a microemulsion. T he catalytic rate constants for the amines containing hydrophilic grou ps increase in microemulsions as compared to those in an aqueous mediu m, while the catalytic constants for the amines containing hydrophobic groups decrease.
