General Description |
A colorless liquid with a sweet pungent taste and odor resembling the odor of oranges. Melting point 20.5°C (68.9°F); freezes under cool conditions. Slightly soluble in water and denser than water. Hence sinks in water. Vapor heavier than air. Flash point 180°F. A mild irritant to skin and eyes. Vapors can be narcotic in high concentrations. Used as a flavoring, solvent, and polymerization catalyst. |

Air & Water Reactions |
Slightly soluble in water. |
|
Reactivity Profile |
Acetophenone reacts with many acids and bases liberating heat and flammable gases (e.g., H2). Reacts with many oxidizing agents. Reacts with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat. The amount of heat in these reactions may be sufficient to start a fire in the unreacted portion. Incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. |
|
Health Hazard |
No toxicity expected from inhalation or ingestion except slight narcotic effect. Liquid can cause eye and skin irritation on contact. |
