其中大多數存於石油的汽油餾出物中。


其直链化合物是正庚烷CH3(CH2)5CH3（沸點98℃）。


汽油發動機中引起爆震，危害極大。



应用


庚烷可以和异辛烷（辛烷值假定为100）配成各种比例的混合物用作测定汽油的辛烷值的标准；正庚烷经脱氢芳构化可制成甲苯。

Volkswagen Group MQB platform

Image
The Volkswagen Group MQB platform is the company's strategy for shared modular design construction of its transverse, front-engine, front-wheel-drive layout (optional front-engine, four-wheel-drive layout) automobiles. Volkswagen spent roughly $60bn [1] developing this new platform and the cars employing it. The platform underpins a wide range of cars from the supermini class to the mid size SUV class. MQB allows Volkswagen to assemble any of its cars based on this platform across all of its MQB ready factories. This allows the Volkswagen group flexibility to shift production as needed between its different factories. Beginning in 2012, Volkswagen Group marketed the strategy under the code name MQB , which stands for Modularer Querbaukasten , translating from German to "Modular Transversal Toolkit" or "Modular Transverse Matrix". [2] [3] MQB is one strategy within VW's overall MB (Modularer Baukasten or modular matrix) program which also includes th...
