| 外观 / 形态 : | A colorless liquid with a sweet pungent taste and odor resembling the odor of oranges.；Acetophenone appears as a colorless liquid with a sweet pungent taste and odor resembling the odor of oranges. Freezes under cool conditions. Slightly soluble in water and denser than water. Hence sinks in water. Vapor heavier than air. A mild irritant to skin and eyes. Vapors can be narcotic in high concentrations.
