2-Bromo-2-nitro-1,3-propanediol Specification

 Bronopol (CAS NO.52-51-7) is a white crystals,would burn easily,it may detonate under strong shock.While heated to decomposion evolving toxic gases. Toxic substances through skin absorption, inhalation or ingestion.

 Bronopol (CAS NO.52-51-7) is a killing bacterial agents,it can effectively control a variety of plant pathogenic bacteria.It is mainly used for cosmetics,leather preservation,widely used in water treatment, pharmaceutical, pesticides, cosmetics, detergent and other industries as preservatives and sterilizing agents, by the nitro-methane and formaldehyde , bromine reaction derived.Invested in the reactor measured nitro-methane, formaldehyde, water and ethanol, 40% liquid caustic soda was added dropwise under cooling at this time there is solid precipitation, and then dropping quantitative bromine, plus completion of mixing, vacuum steam out of part of the water and ethanol, after cooling, crystallization, filtration, drying advanced Bronopol, the yield of above 70%, content is about 93%.

 Bronopol (CAS NO.52-51-7) is a highly-toxic pesticide,burning will produce bromide and nitrogen oxides emitted toxic fumes.Besides should be stored and transported in low-temperature,drying environment. separately with oxidizing agents.Fire extinguishing agents water, carbon dioxide, dry powder, foam would be used if emergency.
