Aggregation and kinetic studies have been performed to understand the hydrolytic potencies of the series of oxime - functionalized surfactants , viz . , 3 - hydroxyiminomethyl - 1 - alkylpyridinium bromide ( alkyl = CnH2n + 1 , n = 10 , 12 , 14 , 16 , 18 ) in the cleavage of phosphate esters , p - nitrophenyl diphenyl phosphate ( PNPDPP ) and bis ( 2 , 4 - dinitrophenyl ) phosphate ( BNDPP ) , in mixed micelles with cetylpyridinium bromide ( CPB ) .
