Synthesis of UV Absorbers of Benzotriazol Structure |
| |
| Abstract: | Seven UV absorbers of benzotriazol structure were prepared by diazotisation, coupling and reduction. Reaction conditions were modified and reaction mechanism was studied. The intermediate compounds of reduction were isolated and identified by IR, MS and H NMR . The relationship between the UV absorption and structure was also explained. |
