Description
Calcium permanganate, also known as permanganate of lime, is a dark purple crystalline solid with the chemical formula Ca(MnO4)2. It is a strong oxidizing agent and possesses disinfectant, deodorizing, and water-purifying properties.
Uses
Used in General Applications:
Calcium permanganate is used as an antiseptic, disinfectant, and deodorizer for various purposes, including water purification and general sanitation.
Used in Textile Industry:
In the textile industry, calcium permanganate is used as a water-sterilizing agent to ensure the cleanliness of water used in the manufacturing process.
Used in Dental Procedures:
Calcium permanganate is employed in dental procedures for its disinfecting and deodorizing properties, promoting a hygienic environment during treatment.
Used in Welding Industry:
With calcium fluoride (CaF2) as a binder, calcium permanganate is used in the production of welding electrode coatings and fluxes, enhancing the welding process and ensuring the quality of the final product.
Chemical Properties:
Calcium permanganate is a violet or dark purple, deliquescent crystal that can be synthesized by reacting potassium permanganate (KMnO4) with calcium chloride (CaCl2). Its strong oxidizing properties make it suitable for various applications, such as disinfection, deodorization, and water purification.
Air & Water Reactions
Water soluble.
Reactivity Profile
CALCIUM PERMANGANATE is an oxidizing agent. Noncombustible but CALCIUM PERMANGANATE will accelerate the burning of combustible material. If the combustible material is finely divided the mixture may be explosive. Contact with liquid combustible materials may result in spontaneous ignition. Contact with sulfuric acid may cause fires or explosions. Mixtures with acetic acid or acetic anhydride can explode if not kept cold [Von Schwartz 1918 p. 34 ]. Explosions can occur when CALCIUM PERMANGANATE that has been treated with sulfuric acid comes in contact with benzene, carbon disulfide, diethyl ether, ethyl alcohol, petroleum, or other organic matter.
Health Hazard
Inhalation, ingestion or contact (skin, eyes) with vapors or substance may cause severe injury, burns or death. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause pollution.
Fire Hazard
These substances will accelerate burning when involved in a fire. Some may decompose explosively when heated or involved in a fire. May explode from heat or contamination. Some will react explosively with hydrocarbons (fuels). May ignite combustibles (wood, paper, oil, clothing, etc.). Containers may explode when heated. Runoff may create fire or explosion hazard.
Safety Profile
Poison by intravenous
route. See also CALCIUM COMPOUNDS,
MANGANESE COMPOUNDS, and
PERMANGANATES. A strong oxidant.
May explode on contact with acetic acid or
acetic anhydride. Ignites on contact with
cellulose. Incompatible with hydrogen
peroxide.
Purification Methods
Crystallise it from water (3.3mL/g) by partial evaporation in a desiccator. It is deliquescent. Note that it loses oxygen more readily than the potassium salt. It is an oxidising agent.
Check Digit Verification of cas no
The CAS Registry Mumber 10118-76-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,1,1 and 8 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 10118-76:
(7*1)+(6*0)+(5*1)+(4*1)+(3*8)+(2*7)+(1*6)=60
60 % 10 = 0
So 10118-76-0 is a valid CAS Registry Number.
