Methylcyclopentadienyl manganese tricarbonyl Chemical Properties,Uses,Production

Chemical Properties

An orange liquid with a pleasant odor. Slightly soluble in water and denser than water. May be toxic by inhalation, ingestion and/or skin absorption. Faintly pleasant, herb-like odor.

Uses

Methylcyclopentadienyl manganese tricarbonyl is used for doping of ZnSe nanocrystals
It can also be used as a reactant for:
Aldol addition reactions
Preparation of homo- and heteronuclear mixed biscarbene complexes with conjugated bithiophene units
Molecular fragmentation using shaped femtosecond laser pulses
Preparation of MnAs thin films grown on GaAs(001) by metalorganic vapour phase epitaxy (MOVPE)

Preparation

Into a reaction flask under nitrogen was placed 1.26 parts bis(methylcyclopentadienyl) manganese (91.8% pure), 0.93 parts manganous acetate, 0.78 parts tetrahydrofuran (THF) and 17.31 parts toluene. Over a period of 15 minutes, a solution of 1.24 parts triethyl aluminum (TEA) in 8.70 parts of toluene was added to the above mixture with a vigorous stirring (Al/Mn atom ratio 1/1, TEA/THF mole ratio 1/1). The solution darkened slightly. This solution of the intermediate complex was transferred under nitrogen to a stainless steel autoclave. The autoclave was sealed, pressurized twice to 300 psig with carbon monoxide and vented and finally pressurized with carbon monoxide to 600 psig and heated while stirring to 100° C. Carbon monoxide was added as needed to maintain 600 psig. After two hours at 100° C., the temperature was raised to 150° C. for 30 minutes. The autoclave was then cooled, vented and discharged. The mixture was hydrolyzed with 10% aqueous HCl. An equal volume of pentane was added to extract the MMT. The pentane phase was analyzed by gas chromoatograph (GC) using a pentadecane internal standard to show a yield of Methylcyclopentadienyl manganese tricarbonyl(MMT) based on manganese of 84% and, based on MCP, of 89%.

Definition

Methylcyclopentadienyl Manganese Tricarbonyl is a dark orange liquid with a faintly pleasant odor. It is used as a fuel additive to abate smoke and as a gasolinc additive in antiknock mixes.

General Description

Methylcyclopentadienyl manganese tricarbonyl (hereinafter "MMT") is an antiknock agent for gasoline discovered in the fifties and sold commercially by Ethyl Corporation. It can be made by the reaction of carbon monoxide with bis(methylcyclopentadienyl) manganese referred to as "carbonylation". 

Air & Water Reactions

Slightly soluble in water.

Reactivity Profile

METHYLCYCLOPENTADIENYLMANGANESE TRICARBONYL decomposes when exposed to light. METHYLCYCLOPENTADIENYLMANGANESE TRICARBONYL is stable in water.

Hazard

Toxic by ingestion, inhalation, and skinabsorption. Central nervous system impairment;lung, liver and kidney damage.

Health Hazard

In concentrated form METHYLCYCLOPENTADIENYLMANGANESE TRICARBONYL is highly toxic by all routes of exposure. Approximately 5-15 ml, when spilled on the hand and wrist of a worker, produced toxic effects within 3-5 minutes.

Fire Hazard

When heated to decomposition, METHYLCYCLOPENTADIENYLMANGANESE TRICARBONYL emits toxic fumes of carbon monoxide. Hazardous polymerization may not occur.

Safety Profile

Poison by ingestion, inhalation, skin contact, intravenous, and intraperitoneal routes. A slimn irritant. When heated to decomposition it emits toxic fumes of CO. See also MANGANESE COMPOUNDS and CARBONYLS.

Potential Exposure

MMT is used as an octane improver in unleaded gasoline, other distillate fuels, and fuel oils; as a smoke abater in fuels.

Shipping

UN3281 Metal carbonyls, liquid n.o.s. Hazard class 6.1. Technical name required, Potential Inhalation Hazard (Special Provision 5).

Incompatibilities

Light causes decomposition. May be air-reactive. A strong reducing agent. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, halogens.

Waste Disposal

Generators of waste (equal to or greater than 100 kg/mo) containing this contaminant, EPA hazardous waste number N450, must conform to USEPA regulations for storage, transportation, treatment, and disposal of waste. Dispose of waste material as hazardous waste using a licensed disposal contractor to an approved landfill. Dispose of contents and container to an approved waste disposal plant. Containers must be disposed of properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office. All federal, state, and local environmental regulations must be observed. Do not discharge into drains or sewers.
