2,4-디메틸펜탄 C화학적 특성, 용도, 생산
화학적 성질
Colorless liquid with an odor resembling heptane. An odor threshold concentration of 940 ppbv was reported by Nagata and Takeuchi (1990).용도
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.환경귀착
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.]2,4-디메틸펜탄 준비 용품 및 원자재
