3-METHYLHEPTANE Usage And Synthesis
- Chemical PropertiesColorless liquid.
- Physical propertiesColorless, flammable liquid with an odor resembling hexane. An odor threshold concentration of 1.5 ppmv was reported by Nagata and Takeuchi (1990).
- UsesCalibration, organic synthesis.
- HazardFlammable, dangerous fire risk.
- Environmental FatePhotolytic. 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 organicsIn 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.
