2,2,5-TRIMETHYLHEXANE Chemical Properties,Usage,Production

Chemical Properties

Colorless liquid.

Physical properties

Clear, colorless, flammable liquid with a faint aliphatic hydrocarbon odor. An odor threshold concentration of 900 ppbv was reported by Nagata and Takeuchi (1990).

Uses

Synthesis, motor-fuel additive.

Hazard

Flammable, dangerous fire risk; the 2,3,3-, 2,3,4-, and 3,3,4-isomers are less flammable.

Environmental Fate

Chemical/Physical. Complete combustion in air produces carbon dioxide and water vapor. 2,2,5-Trimethylhexane will not hydrolyze because it does not contain a hydrolyzable functional group.

Solubility in water

In methanol, g/L: 162 at 5 °C, 179 at 10 °C, 200 at 15 °C, 221 at 20 °C, 247 at 25 °C, 280 at 30 °C, 316 at 35 °C, 360 at 40 °C (Kiser et al., 1961); miscible with hexane and pentane.
