  1. Model Compounds for the Photochemical Study

  2. Mechanism of Coupling Reaction Primary factors controlling the overall reaction need to be understood. Possible approaches include, -Electrochemical oxidation/spectroelectrochemistry -Radiolysis to identify reaction kunetics and mechanism -Medium effects on the reaction kinetics -Identify propagating or quenching reactions

  3. pKa 3.4 pKa 10.4 red blue red Medium Effects • Substituent groups alter the dye color • pH can bring about significant changes in the coloration • oleic acid serves as both buffering agent & surfactant • high surfactant concentration is known to minimize the amount of water which in turn favors the local peroxide concentration

  4. Reactive Dyes Sonolytic Degradation Or Reactive Black 5 Vinodgopal & Kamat, Water Research, 1998, 32,3646-3650 Background information on dyeing of wool and other fibers with reactive dyes may be useful in considering alternate systems
