| 摘 要： | 微乳状液，简称微乳，通常是由表面活性剂、助表面活性剂、水和油形成的澄清、透明、稳定的分散体系．分散相直径一般在20-100nm之间[1].表面活性剂和助表面活性剂通常占微乳的15－25％（质量分数）[2]、典型的助表面活性剂是中等碳键长度的醇．显然，微乳是一种高度分散的间隔

| Abstract: | The catalysis of O/W microemulsions of cetyltrimethylammonium bromide(CTAB),butyl alcohol, benzene and water to the hydrolysis of 2,4-dinitrochlorobenzene(DNCB) was stud-ied. Hydrolysis of DNCB in microemulsions under mormal normal temperature and normal pressure wasrealized. The results showed that the rate constants of hydrolysis of DNCB decreased with theincrease of benzene content and the ratio of cosurfactant to CTAB. As cosurfactant, t-butylalcoholis better than n-butyl alcohol for the reaction. |
