Ammonium persulfate - properties

无色单斜结晶或白色结晶性粉末。熔点120℃（分解），d 1_982。具有很强的氧化性和腐蚀性。完全干燥的过硫酸铵不易分解，潮湿的过硫酸铵会逐渐分解，放出氧气和臭氧。易溶于水，其水溶液在室温下也会分解。与还原剂、有机物、易燃物或金属粉末等混合可形成爆炸性混合物。

Colorless monoclinic crystal or white crystalline powder. Melting point 120 ℃ (decomposition), d 1_ 982。 It has strong oxidation and corrosion. Completely dry ammonium persulfate is not easy to decompose, while wet ammonium persulfate will gradually decompose, giving off oxygen and ozone. Easily soluble in water, its aqueous solution will also decompose at room temperature. It can be mixed with reducing agent, organic substance, inflammable substance or metal powder to form explosive mixture.

过硫酸铵 - 制法

Ammonium persulfate preparation method

利用电解法，由硫酸铵和硫酸配制成电解液，经除杂质后进行电解，HS04在阳极放电生成过二硫酸，再与硫酸铵反应得到过硫酸铵。当阳极液中过硫酸铵含量达到一定浓度后，经过滤、晶、离心分离、干燥即可。

Electrolytic method is used to prepare electrolyte from ammonium sulfate and sulfuric acid. After impurities are removed, the electrolyte is electrolyzed. HS04 generates persulfuric acid in anodic discharge, and then reacts with ammonium sulfate to obtain ammonium persulfate. When the content of ammonium persulfate in the anode solution reaches a certain concentration, it can be filtered, crystallized, centrifuged and dried.

过硫酸铵 - 用途

Ammonium persulfate - use

用作四氟乙烯聚合时的引发剂。也是某些水溶性单体如丙烯酸及其酯、丙烯酰胺、醋酸乙烯酯等聚合或共聚的引发剂。还可用作漂白剂、脱臭剂、氧化剂、蛋白试剂和钢铁的分析试剂。也是制造过硫酸盐和双氧水的原料。

It is used as an initiator in the polymerization of tetrafluoroethylene. It is also an initiator for polymerization or copolymerization of some water-soluble monomers, such as acrylic acid and its ester, acrylamide, vinyl acetate, etc. It can also be used as bleach, deodorant, oxidant, protein reagent and analytical reagent for steel. It is also the raw material for manufacturing persulfate and hydrogen peroxide.
