| Melting Point | -151 °F (USCG, 1999) |
| Boiling Point | 250.3 °F at 760 mmHg (USCG, 1999) |
| Density | 0.715 at 68 °F (USCG, 1999) - Less dense than water; will float |
| Solubility | Miscible with ethanol, ether |
| Flash Point | 70 °F (USCG, 1999) |
| Vapor Pressure | 17.4 [mmHg] |
| Appearance | 1-octene appears as a colorless liquid. Flash point 70 °F. Insoluble in water and less dense (at about 6 lb / gal) than water. Hence floats on water. Vapors are heavier than air and may settle in depressions. Reported to biodegrade very slowly. Used in organic synthesis, surfactants, and plasticizers. |
