| | MANGANESE CARBONYL Usage And Synthesis |
| Chemical Properties | yellow crystalline powder | | Uses | MANGANESE CARBONYL can be used as Catalyst; antiknock additive.
| | Uses | It is used as a catalyst and a fuel additive toincrease octane number. | | Hazard | Toxic material. | | Health Hazard | Toxicity data are not available for this compound.Chronic exposure to its dusts has thepotential to produce damaging effects on thepulmonary system and the central nervous system.Skin or eye contact can cause irritation.When heated, it emits toxic carbon monoxide. | | Fire Hazard | There is no report of any fire or explosion
hazard. However, on the basis of its structure
and analogy with dirhenium decacarbonyl, it may be anticipated to ignite
when heated above 150°C (302°F). The fine
powder is susceptible to produce pyrophoric
tetramer. | | Purification Methods | Golden yellow crystals which in the absence of CO begin to decompose at 110o, and on further heating yield a metallic mirror. In the presence of 3000psi of CO it does not decompose on heating to 250o. It is soluble in common organic solvents, insoluble in H2O, not very stable in air, to heat or UV light. It dissolves in a lot of *C6H6 and can be crystallised from it. It distils with steam at 92-100o. It can be purified by sublimation under reduced pressure (<0.5mm) at room temperature to give well-formed golden yellow crystals. If the sample is orange coloured, this sublimation leads to a mixture of golden-yellow and dark red crystals of the carbonyl and carbonyl iodide, respectively, which can be separated by hand picking under a microscope. Separation followed by resublimations provides the pure compounds. POISONOUS. [Brimm et al. J Am Chem Soc 76 3831 1954, Closson et al. J Am Chem Soc 80 6167 1958, 82 1325 1960.] |
