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.

過(guò)硫酸銨的用途

Application of ammonium persulfate

檢定和測(cè)定錳，用作氧化劑。漂白劑。照相還原劑和阻滯劑。電池去極劑。用于可溶性淀粉的制備。

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、丙烯酸酯等烯類單體乳液聚合的引發(fā)劑，價(jià)格便宜，所得乳液耐水性較好。還用作脲醛樹(shù)脂的固化劑，固化速度最快。亦用作淀粉膠黏劑的助氧化劑，與淀粉成分中的蛋白質(zhì)反應(yīng)提高粘接性，參考用量為淀粉的0.2%~0.4%。也用作金屬銅表面處理劑。

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.

化學(xué)工業(yè)用作制造過(guò)硫酸鹽和雙氧水的原料,有機(jī)高分子聚合時(shí)的助聚劑、氯乙烯單體聚合時(shí)的引發(fā)劑。油脂、肥皂業(yè)用作漂白劑。還用于金屬板蝕割時(shí)的腐蝕劑及石油工業(yè)采油等方面。食品級(jí)用作小麥改質(zhì)劑、啤酒酵母防霉劑。

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.
