摘要：
The acid catalyzed hydrolysis of two N-substituted hydroxamic acids (C6H5CON(OH)R', R'= C6H5 (PBHA), R'= C6H5CH2 (BBHA)) in mixed systems containing beta-cyclodextrin (beta-CD) and a surfactant (sodium dodecyl sulfate, SDS) has been studied. The reactions are inhibited by beta-CD. The inhibition is attributed to the formation of inclusion complex and competition between the micellization and complexation processes.
