The hydrolysis kinetics of 2,4 dinitrochlorobenzene in microemulsion system of cetyltrimethylammonium bromide/n butanol/25% n-octane/water has been studied. The results show that the hydrolysis in W/O microemulsion decreases rapidly with increase of the water content in it, it also true in O/W microemulsion; whereas in B.C. the hydrolysis increases with water con tent. The transition points of the hydrolysis rates occur at the structural transition points from W/O to B C, and B C to O/W. This is considered to be caused by the change of polarity in interfacial films and the size of the particles. The effects of hydrocarbons, alcohols, temperature and NaOH concentration on the hydrolysis rate also have been investigated.
