Perfluoroheptane

n-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.

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]
