Perfluor- n -hexane is a chemical compound from the group of perfluorocarbons , which, due to its inert properties, is used as a heat exchanger and solvent. Use in medicine for lung damage is also being investigated.

Extraction and presentation

Perfluorohexane can be obtained from cobalt (II) fluoride using a Fowler process .

${\displaystyle \mathrm {2\ CoF_{2}+F_{2}\longrightarrow 2\ CoF_{3}} }$

${\displaystyle \mathrm {C_{6}H_{14}+28\ CoF_{3}\longrightarrow } }$ ${\displaystyle \mathrm {C_{6}F_{14}+14\ HF+28\ CoF_{2}} }$

The electrochemical fluorination of trihexylamine according to the gross equation is also possible

${\displaystyle \mathrm {2\ N(C_{6}H_{13})_{3}+90\ HF\longrightarrow } }$ ${\displaystyle \mathrm {6\ C_{6}F_{14}+2\ NF_{3}+45\ H_{2}} }$
