摘要：

The influence of the detergentless water/oil microemulsion formed in the 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 was investigated. The leveling of the catalytic rate constants and basicities of the amines was found for this reaction in a microemulsion. The catalytic rate constants for the amines containing hydrophilic groups increase in microemulsions as compared to those in an aqueous medium, while the catalytic constants for the amines containing hydrophobic groups decrease.
