Production process of ammonium persulfate

过硫酸铵是由硫酸铵和稀硫酸电解后结晶而得。

Ammonium persulfate is crystallized from ammonium sulfate and dilute sulfuric acid after electrolysis.

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，硫酸氢根在阳极放电而生成过二硫酸，再与硫酸铵反应生成过硫酸铵，干燥制得过硫酸铵成品

Electrolysis method is to prepare electrolyte from ammonium sulfate and sulfuric acid. After impurities are removed, electrolysis is carried out. Hydrogen sulfate is discharged at the anode to generate persulfuric acid, and then reacts with ammonium sulfate to generate ammonium persulfate, which is dried to produce finished ammonium persulfate

３．过硫酸铵主要用途

3. Main uses of ammonium persulfate

Ａ．检定和测定锰，用作氧化剂。

A. The determination of manganese as an oxidant.

Ｂ．造纸．油脂、肥皂业用作漂白剂

B. Paper making. Oil and soap industry used as bleach

Ｃ．用作醋酸乙烯、丙烯酸酯、氯乙烯等产品乳液聚合的引发剂，便宜，所得乳液耐水性较好。同时也是苯乙烯，丙烯，丁二烯等乳体发生共聚作用的引发剂。

C. As an initiator for lotion polymerization of vinyl acetate, acrylate, vinyl chloride and other products, the price is cheap, and the obtained lotion has good water resistance. It is also an initiator for copolymerization of styrene, propylene, butadiene and other emulsions.

Ｄ．化学工业用作制造过硫酸盐和双氧水的原料，有机高分子聚合时的助聚剂

D. The chemical industry is used as the raw material for the production of persulfate and hydrogen peroxide, and as the polymerization aid for organic polymer polymerization

Ｅ．金属表面的处理（例如在半导体制造业：印刷电路的清洗和蚀刻），铜和铝表面的活化。

E. Treatment of metal surfaces (e.g. in semiconductor manufacturing: cleaning and etching of printed circuits), activation of copper and aluminum surfaces.

Ｆ．在造纸行业特别是在制浆用作低温漂白

F. Used for low temperature bleaching in paper industry, especially in pulping

４．存储条件

4. Storage conditions

储存于阴凉、干燥、通风良好的库房。远离火种、热源。包装密封，防止受潮。应与还原剂、活性金属粉末等分开存放，切忌混储。储区应备有合适的材料收容泄漏物。

Store in a cool, dry and well ventilated warehouse. Keep away from kindling and heat source. The package shall be sealed to prevent moisture. It shall be stored separately from reductant, active metal powder, etc., and shall not be mixed. The storage area shall be equipped with appropriate materials to contain the leakage.
