use trichloroisocyanuric Acid (TCCA) in the presence of moisture

Positive alcohol in dichloromethane, TEMPO (5 mol%) catalyzed, by trichloroisocyanuric Acid (TCCA) (1.2 eq) oxide, and then in pyridine and hexafluoroisopropanol (2 eq) to form the corresponding hexafluoroisopropyl ester, 14 cases yield 53% to 93%. Hexafluoro isopropyl generated in acetonitrile at room temperature for a primary or secondary amine is reacted with the corresponding amide, 20 cases yield of 81% to 98%, the difference between the nucleophilic primary or secondary amines do not react. Hexafluoro isopropyl or not isolated, one-pot synthesis of amides.
The second required ingredient of the novel composition is an alkali metal bicarbonate. Suitable alkali metal bicarbonates include sodium bicarbonate and potassium bicarbonate, with sodium bicarbonate being preferred. As alkali metal bicarbonates readily react with trichloroisocyanuric Acid (TCCA) in the presence of moisture, it is necessary that the mixture of trichloroisocyanuric acid and alkali metal bicarbonate be substantially anhydrous, that is the mixture should have a moisture content of less than about 0.2 percent and preferably less than 0.1 percent by weight of the mixture. By maintaining the mixture substantially anhydrous, the mixture can be packaged in air tight, humectantly sealed packaging which prevents atmospheric moisture from coming in contact with the product.
Evaluation of different disinfection methods for Brucella disinfecting effect, provide experimental evidence for the establishment of high-level biosafety laboratories and vaccine production workshop sterilization standard Brucella operating specifications. Screening rough and smooth as a model type Brucella bacteria. The pattern of bacteria and high concentrations of bacteria were treated with low concentrations of bacteria UV, chlorine content of 2 000 mg / ml trichloroisocyanuric Acid (TCCA) and 75% ethanol, after 15 min, 30 min, 60 min sterilization treatment, treatment after the bacterial culture at 37 ℃ 5 d, to observe the survival, disinfection effect evaluation. Results ultraviolet light can completely kill the biological safety cabinet in a high concentration and low concentration of brucellosis within 15 min.
