Trichloroisocyanuric acid (TCCA) is one of the sustainable oxidants

Trichloroisocyanuric acid (TCCA) has been recognized as one of the sustainable oxidants. TCCA is readily available, low toxic and less corrosive, and thus it has been widely utilized in organic reactions other than its use in the water purification and sanitization. TCCA was also used as oxidant for the conversion process. Under these reaction conditions, DHA was obtained in 52% yield that is slightly higher than that for carbon supported PteBi catalyst which gave a 44.8% yield. The PteBi catalyst was reported to afford higher activity than others such as Pd/carbon and Pd/TiO2. For comparison, polystyrene supported Pd catalystwas also prepared and examined for the glycerol oxidation reaction. Pd nanoparticles in the catalyst of nano-Pd/polystyrene aggregate heavily. A DHA yield of 27% was obtained with the catalyst under similar conditions. The low activity could be due to catalyst aggregation.
Because of the low toxic and less corrosive, Trichloroisocyanuric acid (TCCA) alway used as  oxidants. It should be pointed out that the support could be separated conveniently by filtration and reused at least 3 times with the yield of 49%, 47% and 50% for the glycerol oxidation reaction under the same conditions. To investigate the leached Pd, the samples of the filtrate plus washings obtained from above standard reactions were subjected to ICP analysis that showed the concentrations of Pd were to be less than 5.0 ppm. In addition, the standard reaction wasconducted with the recovered filtrate, but no product could be isolated. The results suggested that the supported Pd NPs, rather than the leached Pds, provided the active centers. The detailed mechanistic study of the reaction is currently underway in our laboratories.
Trichloroisocyanuric acid (TCCA)  used as oxidant was very common. Carborane-appended styrene monomers were synthesized in high yields. The monomers were able to conduct radical polymerization reactions in the presence of AIBN initiator to produce carborane-appended polystyrenes. Carboranylpolystyrene-coated graphene oxides showed higher combustion temperature when compared to that with pristine GOs. Both the thermal and oxidation stability of the GOs have been improved significantly. In addition, it has been concluded that the well-dispersed, polymer-supported palladium nanoparticle compositewas found to be efficient catalyst for the glycerol oxidation reaction. It is expected that our protecting methodology and prototype catalyst will find broader applications in both academia and industry.
