Chemical Properties
Colorless liquid.
Physical properties
Clear, colorless, flammable liquid with a faint aliphatic hydrocarbon odor. An odor threshold
concentration of 900 ppb
v 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.
