Perfluoroheptane

n-Perfluoroheptane
	Ball-and-stick model of perfluoroheptane
	Coloured water (top) and perfluoroheptane (bottom). Perfluoroheptane is hydrophobic and is denser than water, so it sinks to the bottom and the animals pictured cannot penetrate it.
Names
	Preferred IUPAC name Hexadecafluoroheptane

Perfluoroheptane, C₇F₁₆, (usually referring to the straight chain molecule called n-perfluoroheptane) is a perfluorocarbon.^[2] It is hydrophobic (water-insoluble) and oleophobic (oil-insoluble). It is used in deacidification of paper as a medium carrying powdered magnesium oxide.^[3]
