Trichloroisocyanuric Acid (TCCA) solid is slowly added in an amount sufficient to convert the KI to iodine in situ

Trichloroisocyanuric Acid (TCCA) solid is slowly added in an amount sufficient to convert the KI to iodine in situ. The mixture is agitated by tumbling for 20 min and the supernatant removed. The process may be repeated as necessary until the resin displays an activity about equal to the activity of new iodinated resin.
Tripodal trisilanols tris[4-(diisopropylhydroxysilyl)phenyl]-phenylsilane and -methylsilane (3a and 3b) as well as 1,3,5 tris(diisopropylhydroxysilylmethyl)-2,4,6-triethylbenzene (3c) were synthesized by treatment of the corresponding tribromide with alkyl lithium or magnesium, followed by silylation with diisopropylchlorosilane, halogenation with trichloroisocyanuric acid (TCCA) or N-bromosuccinimide (NBS), and subsequent alkaline hydrolysis.
Trichloroisocyanuric Acid (TCCA) is one of the main varieties of chlorinated acid products, it is a new and efficient, multi-purpose disinfectant, both excellent algae, decontamination, deodorization , bleaching, wool shrink and has other functions. Discussion the disinfection of TCCA for the oral cavity, to provide the basis for practical dentistry disinfection.  Methods:  Hepatitis B e- antigen-positive serum samples were contaminated standard dental impression with water and TCCA the model irrigation system, respectively.
