Description and Uses

n-Hendecane, also known as Undecane and Hendecane, is a component of petrol. It is used as a solvent and degreaser for inks as well as in organic synthesis. Due to its low phase transition temperature (-26 °C), it is also used as a core material for microcapsules in cold chain transport.

Undecane is used in preparation method of small-size hollow Silicon Dioxide.
