The effects factors on trichloroisocyanuric Acid (TCCA) disinfectants

Trichloroisocyanuric Acid (TCCA) disinfectant effect, will cause different changes according to various environmental factors? How to make disinfection to maximize? What are the factors that can affect its use?
1. The effect of temperature on TCCA disinfectants
In general, most TCCA disinfectants at low temperature sterilization effect is poor, when the temperature is below 16 ℃, the general TCCA disinfectants for most pathogens are useless, trichloroisocyanuric cyanuric acid disinfectant to kill microorganisms force is enhanced with increasing temperature, the temperature can increase the effect of anti-virus is not a disinfectant enhanced anti-virus effect. But the temperature rise must not reach the disinfectants themselves are exposed to the limit in order to avoid evaporation and decomposition of the disinfectant active ingredient, affecting disinfection.
2. Humidity on TCCA disinfectants
Different disinfectants have their corresponding humidity range, solid disinfectant (TCCA), soluble in water, when the swimming pool disinfection, an appropriate increase indoor relative humidity, can significantly enhance the sterilizing effect . But too much moisture it will affect the contact area between the TCCA disinfectants and microbes, thus affecting disinfection.
3. PH value of the environmental 
There are about two aspects that affecting disinfection. First, microbial growth and reproduction, second is the impact on the trichloroisocyanuric Acid (TCCA) disinfectant properties, different PH range of different disinfectants adaptation, some sterilizing effect with the increase of PH value is enhanced; some PH the lower the value, the stronger the effect of sterilization.
So when we disinfect the object, we should correctly understand the impact of these factors on the TCCA disinfectants, and strive to allow play to maximize the effect of disinfection.

Typical Procedure for the Epoxidaiton of Enones: Procedure A for non-asymmetric epoxidadtion of 1a-1j, Procedure B for non-asymmetric epoxidation of 1k and Procedure C for asymmetric variants of 1a-1k. Procedure A: To a solution of chalcone (208mg, 1.00 mmol) and TBAB (16mg, 0.05 mmol) in toluene (3 ml) was added  trichloroisocyanuric Acid (TCCA) (233 mg, 1.00 mmol) and then KOH (336mg, 6.00mmol) by portions at 10oC. The biphasic mixture was stirred at 10oC until chalcone disappeared (detected by TLC), followed by addition of ether and filtration. The filtrate was washed with water and dried over MgSO4. Evaporation of the solvents and purification of the residue on silica gel column with 50:1 petroleum ether / ethyl acetate as eluents gave the epoxidation products.
