| Hazard Information | Back Directory | [Hazard]
Flammable, dangerous fire risk. | [Chemical Properties]
Colorless liquid. | [Physical properties]
Colorless, flammable liquid with an odor resembling hexane. An odor threshold concentration of
1.5 ppmv was reported by Nagata and Takeuchi (1990). | [Definition]
ChEBI: 3-Methylheptane is an alkane. | [Environmental Fate]
Photolytic. Based on a photooxidation rate constant of 8.90 x 10-12 cm3/molecule?sec for the
reaction of 3-methylheptane and OH radicals, the estimated lifetime is 16 h during summer
sunlight (Altshuller, 1991).
Chemical/Physical. Complete combustion in air produces carbon dioxide and water vapor. 3-
Methylheptane will not hydrolyze because it does not contain a hydrolyzable functional group. | [Solubility in organics]
In methanol, g/L: 154 at 5 °C, 170 at 10 °C, 190 at 15 °C, 212 at 20 °C, 242 at 25 °C, 274 at 30
°C, 314 at 35 °C, 365 at 40 °C (Kiser et al., 1961); miscible in many liquid hydrocarbons,
particularly saturated hydrocarbons. |
