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.

Flammability and Explosibility

Nonflammable

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.

General Description

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.
