Permanganate of potash: potassium permanganate ... For reference, prices in November 2011 were about US$470 per tonne, but as of May 2013 were stable at US$393. [42]
Potassium permanganate is an inorganic compound with the chemical formula KMnO 4. It is a purplish-black crystalline salt, which dissolves in water as K + and MnO ...
Apart from structural wood preservation measures, there are a number of different chemical preservatives and processes (also known as timber treatment, lumber treatment or pressure treatment) that can extend the life of wood, timber, and their associated products, including engineered wood. These generally increase the durability and resistance ...

Potassium permanganate will decompose into potassium manganate, manganese dioxide and oxygen gas: 2 KMnO 4 → K 2 MnO 4 + MnO 2 + O 2. This reaction is a laboratory method to prepare oxygen, but produces samples of potassium manganate contaminated with MnO 2. The former is soluble and the latter is not.
Nick Teichtmann (R,) with the help of Lowe's employee Jaime Solis, buys lumber to renovate his house by adding a gazebo on top of a deck and fixing his garage at Lowe's home improvement store on ...
Permanganic acid has also been prepared through the reaction of hydrofluorosilicic acid with potassium permanganate, [4] through electrolysis, and through hydrolysis of manganese heptoxide, though the last route often results in explosions. [5] Crystalline permanganic acid has been prepared at low temperatures as the dihydrate, HMnO 4 ·2H 2 O. [3]
