Description and Uses

Chromium carbonyl is a colorless crystallinesubstance which sinters (forms a coherent mass withoutmelting) at 90℃. Molecular weight =220.06; Freezing/Melting point =110℃ (decomposes). Boilingpoint 5 explodes (in lieu of boiling) at 210℃. HazardIdentification (based on NFPA-704 M Rating System):Health 2, Flammability 1, Reactivity 0. Insoluble in water;possible reaction.

It is used as a catalyst for polymerization andisomerization of olefins. It is also used as anadditive to gasoline, to increase the octanenumber.
