Use trichloroisocyanuric Acid (TCCA) and 2,2,6,6-tetramethylpiperidine 1-oxide (TEMPO) co-oxidation system

Banana sheath rot disease in recent years, emerging diseases, there is no production of the potent agent, 2012 - May 2013 were trichloroisocyanuric Acid (TCCA) evaluation of the inhibitory effect of banana sheath rot disease. The test results show that the two-year, 42% wettable powder TCCA is better suppression agent banana sheath rot disease, 336 times 4 times spraying banana sheath rot control effect reached 63.16%, 66.15%, significantly 50% better than the control agent chlorine bromine isocyanurate WP 348 times spraying 4 times the control effect, worth banana producing application.
Use trichloroisocyanuric Acid (TCCA) and 2,2,6,6-tetramethylpiperidine 1-oxide (TEMPO) co-oxidation system alternative classic chromic acid oxidation system to complete the synthesis of benzocaine, avoiding the chromic acid oxidation system toxicity, pollution, post-processing difficulties and other unfavorable environmental factors. a total oxidation system safety, environmental protection, with the reaction yield, short reaction time, mild reaction conditions, the experimental phenomena obvious and easy to operate.
The novel compositions of the present invention include trichloroisocyanuric acid (TCCA) which is a commercially available compound having an available chlorine concentration in the range of from about 89 to about 91.5 percent. Trichloroisocyanuric Acid (TCCA) is produced by known processes such as those described, for example, in U.S. Pat. Nos. 3,757,018, issued Sept. 4, 1973, to R. N Mesiah; 3,810,982, issued May 14, 1974, to R. N. Mesiah; 3,835,134, issued Sept. 10, 1974, to H. W. Schiessl et al; and 3,835,135, issued Sept. 10, 1974, to D. L. Sawhill. When placed in a water body such as a swimming pool, trichloroisocyanuric acid dissolves slowly to release its available chlorine concentration and sanitize the water body. The solubility rate, for example, for tablets containing 5 grams of trichloroisocyanuric acid in water at 25° C. is about 0.1 gram per hour.
