Abstract

The paper reports near-selective nitration of phenol to ortho-nitrophenol using CTAB microemulsion solution in the presence of dilute nitric acid. The difference betweem the selective nitration of different kinds of surfactants such as AOT (anionic surfactant) and CTAB (cationic surfactant) has been investigated. All these experimental results indicate that microemulsions can be selective to give the ortho-phenol.
