CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | N-amyl acetate appears as a mixture of isomers. A clear colorless liquid with a banana-like odor. Flash point varies from 65 °F to 95 °F. Less dense (at 7.2 lb / gal) than water and slightly soluble in water. Hence floats on water. Vapors heavier than air. |
