Beschreibung
Manganese, an essential nutrient, occurs in many foods of plant and animal origin. The naturally occurring manganese levels vary from about 2 0 ppm in nuts, cereals, dried fruits and non-leafy vegetables to less than 1 ppm in animal products. Manganous chloride tetrahydrate is pink translucent crystals which are very soluble in water.1 .
Chemische Eigenschaften
MnCl2 is rose-colored deliquescent crystals that are very soluble in water,and melts at 650°C and boils at 1190°C. The tetrahedral form, MnCI2.4H20 , melts at 58°C and loses its water at 198°C and is used as a catalyst in paints,dyes,pharmaceuticals, and fertilizers, and for various other purposes.
Verwenden
Manganese Chloride is a source of manganese that functions as a nutrient and dietary supplement. it exists as crystals which are readily soluble in room temperature (22°c) water and are very soluble in hot water. see manganese.
Verwenden
Used mainly in the production of dry cell batteries
Verwenden
A novel high-spin hexanuclear Mn(III) cluster, [NaMn6(OMe)12(dbm)6]+, was synthesized via MnCl2 oxidation with simultaneous NaOMe promoted aggregation. This cluster has an unprecedented cyclic structure and 24 unpaired electrons in its ground state.1 Also used in the formation of an active Mn(0) species useful for radical cyclization reactions.2
Verwenden
Manganese chloride (MnCl2) is used in the pharmaceutical industry as a dietary supplement and is added to fertilizers.
Allgemeine Beschreibung
Manganese (II) chloride (MnCl₂) might play a key role in integrin activation. Manganese is indispensable for brain function and is an essential cofactor for several key enzymes like superoxide dismutase and enzymes involved in neurotransmitter synthesis. Manganese can modulate iron and calcium homeostasis. Manganese is also used in the magnetic resonance imaging to increase contrast while examining neuronal connections and brain cytoarchitecture. High levels of manganese is toxic to central nervous system and causes Parkinson′s like symptoms called as manganism. MnCl₂ has been used in reverse transcription reaction mix to enhance the template-switching efficiency.
Sicherheitsprofil
Poison by intraperitoneal, subcutaneous, intramuscular, intravenous, and parenteral routes. Moderately toxic by ingestion. Experimental teratogenic and reproductive effects. Questionable carcinogen with experimental carcinogenic data. Mutation data reported. Explosive reaction when heated with zinc foil. Reacts violently with potassium or sodium. When heated to decomposition it emits toxic fumes of Cl-. See also MANGANESE COMPOUNDS and CHLORIDES.
läuterung methode
It crystallises from water (0.3mL/g) on cooling. The red-rose tetrahydrate melts at ~52o and forms the dihydrate salt which loses all its H2O at 198o to give MnCl2. It is soluble in EtOH.
