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.

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]
