Perfluorotripentylamine is an organic compound with the chemical formula N((CF2)4CF3)3. A molecule of this chemical compound consists of three pentyl groups connected to one nitrogen atom, in which all of the hydrogen atoms are replaced with fluorine atoms. It is a perfluorocarbon. It is used as an electronics coolant, and has a high boiling point. It is colorless, odorless, and insoluble in water. Unlike ordinary amines, perfluoroamines are of low basicity. Perfluorinated amines are components of fluorofluids, used as immersive coolants for supercomputers.[1]

It is prepared by electrofluorination of the amine using hydrogen fluoride as solvent and source of fluorine:[1]

N((CH2)4CH3)3 + 33 HF → N((CF2)4CF3)3 + 33 H2

Safety

Fluoroamines are generally of very low toxicity, so much that they have been evaluated as synthetic blood.[1]
