    Notes: Abstract We have continued our kinetics investigation of the iodosobenzoate (IBA) catalysis of the hydrolysis of p-nitrophenyl diphenyl phosphate (PNDP), in microemulsion media composed of hexadecane in water stabilized by cetyltrimethylammonium bromide and 1-butanol over a range of water mass fractions. We have examined two iodosobenzoic acid derivatives (5-nitro-2-iodosobenzoic acid and 5-octyloxy-2-iodosobenzoic acid) as catalysts. In addition, we have determined by31P FT-NMR techniques that the major product of the hydrolysis of PNDP, both in IBA catalyzed and in uncatalyzed media, is diphenylphosphate.

    Notes: The relationship between apparent diffusion coefficients, D′, of electroactive probe and thc microstructure of an oil-in-water anionic microemulsion, sodium dodecyl sulfate (SDS)/dodecane/I-pentanol/0.1M NaCIaq has been investigated. Three probes, ferrocene (Fc), Fe(CN)63- and methyl viologen (MV2+) allowed the effect of ditrerent microstructure and interactions on the D′-values to be investigated. The results indicate that the droplet as well as hicontinuous microemulsion structures can be identified and point to the effects of cross- phase exchange, partitioning, and multiple binding on the D′-values.
