The chemical dictionary introduces you to the use and operation precautions of ammonium persulfate. Ammonium persulfate is white crystal or powder, odorless. Dry pure ammonium persulfate can be stable for several months. When it is damp, it gradually decomposes into ozone containing oxygen, and when heated, it decomposes into oxygen and becomes ammonium pyrosulfate. Ammonium persulfate is easily soluble in water. The aqueous solution is acidic and gradually decomposes at room temperature. At higher temperatures, it decomposes quickly to release oxygen and produce ammonium bisulfate.

过硫酸铵的用途

Application of ammonium persulfate

检定和测定锰，用作氧化剂。漂白剂。照相还原剂和阻滞剂。电池去极剂。用于可溶性淀粉的制备。

Manganese is verified and determined as an oxidant. bleaching agents. Photographic reductants and blockers. Battery depolarizer. It is used for the preparation of soluble starch.

用作醋酸乙烯、丙烯酸酯等烯类单体乳液聚合的引发剂，价格便宜，所得乳液耐水性较好。还用作脲醛树脂的固化剂，固化速度最快。亦用作淀粉胶黏剂的助氧化剂，与淀粉成分中的蛋白质反应提高粘接性，参考用量为淀粉的0.2%~0.4%。也用作金属铜表面处理剂。

As an initiator for vinyl acetate, acrylate and other olefin monomer lotion polymerization, the price is cheap, and the obtained lotion has good water resistance. It is also used as the curing agent of urea formaldehyde resin, with the fastest curing speed. It is also used as a co oxidant of starch adhesive. It reacts with proteins in starch components to improve adhesion. The reference dosage is 0.2% - 0.4% of starch. It is also used as a surface treatment agent for metallic copper.

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、氯乙烯单体聚合时的引发剂。油脂、肥皂业用作漂白剂。还用于金属板蚀割时的腐蚀剂及石油工业采油等方面。食品级用作小麦改质剂、啤酒酵母防霉剂。

In the chemical industry, it is used as a raw material for the manufacture of persulfate and hydrogen peroxide, a polymerization promoter for the polymerization of organic polymers, and an initiator for the polymerization of vinyl chloride monomers. The oil and soap industry is used as bleaching agent. It is also used as a corrosion agent in metal plate cutting and oil extraction in petroleum industry. Food grade is used as wheat modifier and beer yeast mildew inhibitor.
