- CAS Number
- 7722-64-7
- EC Number
- 231-760-3
- Chemical Name
- Potassium Permanganate
- Chemical Family
- Potassium Salts
AQUOX® POTASSIUM PERMANGANATE is a free-flowing Grade which is recommended where AQUOX® potassium permanganate is subjected to high humidity conditions and where the material is to be dry fed through a chemical feeder or stored in a bin or hopper. Crystals or granules are dark purple with a metallic sheen, sometimes with a dark bronze-like appearance. Free-Flowing Grade is gray due to an additive. AQUOX has a sweetish, astringent taste and is odorless.

- Corrosive Material
AQUOX potassium permanganate is compatible with many metals and synthetic materials. Natural rubbers and fibers are often incompatible. Solution pH and temperature are also important factors. The material must be compatible with either the acid or alkali also being used.; In neutral and alkaline solutions, AQUOX is not corrosive to iron, mild steel, or stainless steel; however, chloride corrosion of metals may be accelerated when an oxidant such as AQUOX is present in solution. Plastics such as polypropylene, polyvinyl chloride Type I (PVC I), epoxy resins, fiberglass reinforced plastic (FRP), Penton, Lucite, Viton A, and Hypalon are suitable. Teflon FEP and TFE, and Tefzel ETFE are best. Refer to Material Compatibility Chart.; Aluminum, zinc, copper, lead, and alloys containing these metals may be (slightly) affected by AQUOX solutions. Actual studies should be made under the conditions in which the product will be used.

- Handling, Storage, and Incompatibility
Protect containers against physical damage. When handling AQUOX, respirators should be worn to avoid irritation of or damage to mucous membranes. Eye protection should also be worn when handling potassium permanganate as a solid or in solution.; AQUOX is stable and will keep indefinitely if stored in a cool, dry area in closed containers. Concrete floors are preferred to wooden decks. To clean up spills and leaks, follow the steps recommended in the SDS. Be sure to use goggles, rubber gloves, and respirator when cleaning up a spill or leak.; Avoid contact with acids, peroxides, and all combustible organic or readily oxidizable materials including inorganic oxidizable materials and metal powders. With hydrochloric acid, chlorine gas is liberated. AQUOX is not combustible, but will support combustion. It may decompose if exposed to intense heat. Fires may be controlled and extinguished by using large quantities of water.
