ammoniumpersulfaatti

Ammoniumpersulfaatti is a chemical compound with the formula (NH₄)₂S₂O₈. It is an inorganic salt that appears as a white crystalline solid. This compound is a strong oxidizing agent and is soluble in water.

The primary applications of ammonium persulfaatti stem from its oxidizing properties. It is widely used as an initiator in polymerization reactions, particularly for polymers like polyethylene, polyvinyl acetate, and polystyrene. In the electronics industry, it serves as an etchant for printed circuit boards. Furthermore, ammonium persulfaatti finds use in hair bleaching formulations and as a cleaning agent. It can also be employed in textile processing and for desizing cotton.

Ammonium persulfaatti is synthesized by the electrolysis of ammonium bisulfate or ammonium sulfate. During this process, persulfate ions are formed. The compound is relatively stable under dry conditions but can decompose when exposed to moisture or heat, releasing oxygen.

When handling ammonium persulfaatti, appropriate safety precautions are necessary due to its oxidizing nature. It can cause irritation to skin, eyes, and the respiratory tract. Contact with combustible materials should be avoided as it can increase the risk of fire.
