Exposure to high levels of dust can also cause difficulty in breathing. In 1908, John William Turrentine used a dilute ammonium persulfate solution to etch copper. CAS No. The bases, are most commonly used as catalysts, are tertiary amines such as N,N,N',N'-tetramethylethylenediamine (TEMED) or 3-dimethylaminopropionitrile (DMAPN). [9] Furthermore, it has been suggested that exposure to ammonium persulfate can cause asthmatic effects in hair dressers and receptionists working in the hairdressing industry. Ammonium sulfate not dependent upon the ammonium sulfate produced within the system can be used as a main feedstock, which is advantageous for industrial purposes. The delayed release … Acidic solutions dissolve iron violently, [Mellor, 1947, Vol. [8], It has been noted that persulfate salts are a major cause of asthmatic effects in women. AMMONIUM PERSULFATE is a potent oxidizing agent. Ammonium persulfate has been used for the preparation of polyacrylamide gels and acrylamide hydrogels. Strong oxidizer. It is also known by other names such as ammonium peroxydisulfate, diammonium persulfate, and diammonium peroxydisulfate. Belongs to the Following Reactive … A mixture with sodium peroxide will explode if subjected to friction (crushing in a mortar), heating, or if a stream of carbon dioxide is passed over it [Mellor 10:464 1946-47].
