Condy's crystals; permanganate of potash; chameleon mineral; potassium manganate(VII)

CAS 7722-64-7

Chemical Formula KMnO₄

Molecular Weight 158.03 g/mol

Potassium permanganate (KMnO4), also known as Condy's crystals, is a dark purple, crystalline compound. It's a strong oxidizing agent, meaning it readily accepts electrons from other substances. This property makes it useful in various applications like water purification, disinfection, and as a chemical reagent. KMnO4 is also used in medicine for treating skin conditions and fungal infections.

Industrial Uses

1. Water Treatment

  • Oxidizer: Potassium permanganate (KMnO4) is used in water treatment as a powerful oxidizing agent to remove dissolved impurities like iron, manganese, and hydrogen sulfide. It also helps to break down organic pollutants and control bacteria growth.

2. Pharmaceuticals

  • Antiseptic and Disinfectant: Potassium permanganate's oxidizing properties make it effective against bacteria, viruses, fungi, and protozoa. This helps prevent infections and clean wounds. It's commonly used to treat skin conditions like impetigo, pemphigus, dermatitis, and tropical ulcers..

3. Performance Chemicals

  • Oxidation of Organic Compounds: KMnO4 can oxidize a wide range of organic compounds, including alcohols, aldehydes, alkenes, and alkynes. It can oxidize alcohols to carbonyls (aldehydes and ketones) and aldehydes to carboxylic acids. Alkenes can be oxidized to glycols, and alkynes can be oxidized to diones.
  • Synthesis of Specific Compounds: KMnO4 is used in the synthesis of important compounds like ascorbic acid, chloramphenicol, and pyrazinoic acid.
  • Baeyer's Reagent: An alkaline potassium permanganate solution is known as Baeyer's Reagent and is used to test for unsaturation in organic compounds. A positive test will result in the decolorization of the KMnO4 solution from purple to pink or brown.
  • Redox reactions: It can oxidize various organic compounds, including alkenes, alcohols, aldehydes, and alkynes, leading to the formation of diols, carbonyls, carboxylic acids, and diones, respectively.

4. Fabric Solutions

  • Bleaching and Oxidizing Agent: KMnO4 is a strong oxidizing agent, meaning it can remove color or change the chemical structure of other substances. In the context of fabrics, it acts as a bleaching agent, particularly in denim where it removes indigo dye to create a lighter, more faded appearance.

5. Metal Treatment

  • Cleaning and Degreasing: Potassium permanganate, especially in alkaline solutions, is effective at removing high-temperature oxides (heat scale) from metal surfaces, like those found on jet engines.
