| 2,2-Dimethylbutane Usage And Synthesis |
| Chemical Properties | 2,2-dimethylbutane is the chain isomeric form of hexane. It is a colorless and flammable liquid with a specific gravity of 0.6444. Insoluble in water, miscible with alcohol, ether, acetone, benzene and petroleum ether. The solubility is similar to that of hexane and 2-methylpentane. |
| Physical properties | Clear, colorless liquid with a mild petroleum-like odor. Liquid quickly evaporates and forms conbustible fumes. An odor threshold concentration of 20 ppmv was reported by Nagata and Takeuchi (1990). |
| Uses | 2,2-Dimethylbutane is an acyclic alkane. Its Research Octane Number (RON) has been reported to be 91.8. It is used to Component of high-octane motor and aviation fuels, intermediate for agricultural chemicals. |
| Application | 2,2-Dimethylbutane may be employed as probe to investigate the nature of possible active sites in supported metal catalysts.
Some of the reported applications of 2,2-dimethylbutane include:
Palladium-catalyzed radical oxidative alkoxycarbonylation to prepare various alkyl carboxylates.
Iridium-iron-catalyzed tandem dehydrogenation-isomerization-hydrosilylation to synthesize corresponding silane. |
