摘要：
Study of the kinetics of alkaline hydrolysis of alkyl p-nitrophenyl chloromethylphosphonates in micellar solutions of cetylpyridinium bromide showed that the observed rate constant depends an the hydrophobicity of the substrates. A minor increase in the length of the alkyl chain in the substituent increases the catalytic effect in the series Et < Bu < C6H13. Further increase in the substrate hydrophobicity results in a decrease in the bimolecular rate constant in the micellar phase.
