过硫酸铵是一种白色、无味晶体，常作强氧化剂使用，(NH4)2S2O8无色单斜晶体，有时略带浅绿色，比重1.982，在120摄氏度分解，放出氧气，生成焦硫酸铵(NH4)2S2O7。干燥时稳定，含水时逐渐分解，放出氧气和臭氧。溶于水，加热即分解。用作试剂、氧化剂、脱臭剂、漂白剂等。由浓硫酸铵溶液电解氧化后结晶而制得也可用作单体聚合引发剂。它几乎不吸潮，由于能达到很高的纯度而具有特别好的稳定性，便于储存。另外，它还具有使用方便、等优点。用途：过硫酸铵是乳胶或丙烯酸单体聚合液、醋酸乙烯、氯乙烯等产品的引发剂，同时也是苯乙烯、丙烯腈、丁二烯等胶体发生共聚作用的引发剂。作为一种强氧化剂有以下用途：
Ammonium persulfate is a white, odorless crystal, often used as a strong oxidant. (NH4) 2S2O8 colorless monoclinic crystal, sometimes slightly greenish, with a specific gravity of 1.982, decomposes at 120 degrees Celsius, releases oxygen, and generates ammonium pyrosulfate (NH4) 2S2O7. It is stable when it is dry, and gradually decomposes when it contains water, releasing oxygen and ozone. Dissolve in water and decompose when heated. Used as reagent, oxidant, deodorant, bleach, etc. It can also be used as initiator for monomer polymerization. It hardly absorbs moisture, and has excellent stability and is convenient for storage because of its high purity. In addition, it also has the advantages of convenient use and safety. Use: ammonium persulfate is the initiator of latex or acrylic monomer polymerization solution, vinyl acetate, vinyl chloride and other products, and is also the initiator of copolymerization of styrene, acrylonitrile, butadiene and other colloids. As a strong oxidant, it has the following uses:
(1)用于金属表面的清洁和酸洗。
(1) For cleaning and pickling of metal surfaces.
(2)用于加快低浓度福尔马林粘合剂的处理过程。
(2) It is used to speed up the treatment process of low concentration formalin adhesive.
(3)是淀粉的调节剂，并应用于粘和剂和涂料中。
(3) It is a regulator for the production of starch and is used in the production of adhesives and coatings.
(4)用于硫酸铵的精制。
(4) Used for refining ammonium sulfate.
(5)是染发剂的基本成分之一，起脱色作用。
(5) It is one of the basic components of hair dyes and plays a role in decolorization.
