Free-radical mechanism of photodecomposition of dyes in solution

  • Published:
Bulletin of the Academy of Sciences of the USSR, Division of chemical science Aims and scope

Conclusions

  1. 1.

    The contribution of the free-radical mechanism to photodecomposition in deoxygenated solutions of rhodamine 6G and azo dyes was determined quantitatively.

  2. 2.

    In the presence and absence of oxygen, the azo dyes studied are photoinitiators of free radical transformations of repeated effect with a high initiation coefficient.

  3. 3.

    The rate constants of the chemical reaction of alkyl and peroxide radicals of the solvent with a number of azo, anthraquinone, and xanthene dyes were obtained.
