Properties
White crystals. Melting point of 125°C, it can soluble in common organic solvents (such as acetone, benzene, dimethylformamide, ethanol, polyethylene glycol, etc. ), slightly soluble in water (25 °C, 100g water dissolved 1.5g). Its aqueous solution is more stable under acidic conditions, and easy hydrolysis in alkaline conditions. Increasing the pH value, heating with ultraviolet light or fluorescent light, can make its dissolution rate greatly accelerated. Easy to be reductant, such as hydrogen bromide and bromine into non-toxic cyanide acetamide, the sterilization rate greatly reduced. When its pH value increase from 6.7 to 9.7, the half-life will change from 37.0h into 0.11h.
Storage
Storage in shady room and dry place.
Solubility
In water, 1.5 g/100 mL (15,000 mg/L)
Application
It is used as anti-microbial agent, controlling bacterial, fungal and algal growth in industrial water systems like cooling towers, pulp and paper mill process water, oil-recovery systems and air-conditioning systems. It is a chemical additive to control bacterial contamination in ethanol fermentation.
