2,4-DIMETHYLPENTANE Chemical Properties,Usage,Production

Chemical Properties

Colorless liquid with an odor resembling heptane. An odor threshold concentration of 940 ppbv was reported by Nagata and Takeuchi (1990).

Uses

It is not only used for synthesizing WeiNiGuan, but also used in binder and coating industry. It is used for synthesizing resin fiber. It is also used as intermediates and adhesives in oil drop coagulation thickener.

Source

In diesel engine exhaust at a concentration of 0.3% of emitted hydrocarbons (quoted, Verschueren, 1983). Schauer et al. (1999) reported 2,4-dimethylpentane in a diesel-powered medium-duty truck exhaust at an emission rate of 410 μg/km.
California Phase II reformulated gasoline contained 2,2-dimethylbutane at a concentration of 15,700 mg/kg. Gas-phase tailpipe emission rates from gasoline-powered automobiles with and without catalytic converters were 2.92 and 354 mg/km, respectively (Schauer et al., 2002).

Environmental Fate

Photolytic. Based on a photooxidation rate constant of 5.0 x 10-12 cm3/molecule?sec for the reaction of 2,3-dimethypentane and OH radicals in air, the half-life is 27 h (Alltshuller, 1991).
Chemical/Physical. Complete combustion in air yields carbon dioxide and water vapor. 2,4- Dimethylpentane will not hydrolyze because it has no hydrolyzable functional group.

Purification Methods

Extract it repeatedly with conc H2SO4, wash with water, dry and distil it. Alternatively percolated it through silica gel (previously heated in nitrogen to 350o). Purify it by azeotropic distillation with EtOH, followed by washing out the EtOH with water, drying and distilling. [Beilstein 1 IV 406.]
