2,4-DIMETHYLPENTANE Chemical Properties,Uses,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.
Synthesis
In a 6 ml autoclave, 2.0 mmol of 2,4-dimethyl-1,3-pentadiene and 0.0136 g of crosslinked poly(styrene-divinylbenzene)-coated encapsulated SiO2 carrier-loaded nanoparticles of Pd metal catalysts were added. After the air in the kettle was displaced three times with carbon dioxide, the kettle was heated to 40 C, 3 MPa hydrogen and 8 MPa carbon dioxide were introduced, and the reaction was carried out under magnetic stirring for 16 h. After the reaction, the ice-water mixture was cooled down, slowly deflated, and centrifuged in ultracentrifugation, and the supernatant was analyzed by gas chromatography, and the corresponding products were 2,4-dimethyl-2-pentene, 2,4-dimethyl-1-pentene, and 2,4-dimethylpentane.
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/moleculesec 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.]
Toxics Screening Level
The initial threshold screening level (ITSL) for 2,4-dimethylpentane is 3,500 μg/m3 based on an 8 hr. averaging time.
