| Chemical Properties | Back Directory | [Appearance]
Colorless gas; disagreeable odor. Readily polymerizes; cannot be shipped or stored in a
gaseous state. | [Uses]
Acetylating agent, generally reacting with compounds having an active hydrogen atom; reacts with
ammonia to give acetamide. Starting point for making various commercially important products, especially acetic anhydride and acetate esters. |
| Hazard Information | Back Directory | [Hazard]
Toxic by inhalation, strong irritant to skin
and mucous membranes. | [Chemical Properties]
Colorless gas; disagreeable odor. Readily polymerizes; cannot be shipped or stored in a
gaseous state. | [Definition]
A member of a
group of organic compounds, general formula
R2C:CO, where R is hydrogen or an
organic radical. The simplest member is
the colorless gas ketene, CH2:CO; the
other ketenes are colored because of the
presence of the double bonds. Ketenes are
unstable and react with other unsaturated
compounds to give cyclic compounds. |
