Abstract
- The hydrolysis of cephanone in water, cetyl trimethyl ammonium bromide(CTAB) micelle, and CTAB/n-C5H11OH/H2O O/W microemulsion was studied through UV-VIS absorption spectroscopy. The mechanism of the hydrolysis and the effects of both the acidity of the media and the composition of O/W microemulsion on the hydrolysis were studied. The results show that the hydrolysis rate of cephanone increases with the acidity. Compared with water, CTAB micelle and CTAB/n-C5H11OH/H2O O/W microemulsion suppress this hydrolysis. The inhibition of the hydrolysis of cephanone by CTAB micelle and CTAB/n-C5H11OH/H2O O/W microemulsion is related to the location of cephanone in the interphases of CTAB micelles and CTAB/n-C5H11OH/H2O O/W microemulsion droplets.
