The Uses of CYCLOPENTADIENYLMANGANESE TRICARBONYL

Cyclopentadienylmanganese tricarbonyl is an important raw material and intermediate used in organic synthesis, pharmaceutical intermediates.

The Uses of CYCLOPENTADIENYLMANGANESE TRICARBONYL

Antiknock agent.

The Uses of CYCLOPENTADIENYLMANGANESE TRICARBONYL

Octane enhancer for gasoline

General Description

Bright yellow, crystalline solid with a camphor-like odor. Sublimes 75-77°C. Slightly soluble in water. Used as an octane enhancement additive for unleaded gasoline.

Reactivity Profile

MANGANESE CYCLOPENTAHIENYL TRICARBONYL is combustible. Heating causes evolution of carbon monoxide and other toxic or irritating gases. Heating in a confined space causes a rise in pressure with the risk of bursting. Incompatible with oxygen.

Hazard

Toxic material absorbed by skin. Central nervous system impairment and skin irritant.

Health Hazard

Manganese cyclopentadienyl tricarbonyl (MCT) causes convulsions and pulmonary edema in laboratory animals.

Safety Profile

A poison by ingestion, inhalation, intraperitoneal, and intravenous routes. A mild narcotic which can damage kidneys. When heated to decomposition it emits acrid smoke and irritating fumes. See also MANGANESE COMPOUNDS and CARBON MONOXIDE.
