What is PERFLUORO(METHYLCYCLOHEXANE)?

Chemical properties

CLEAR LIQUID

The Uses of PERFLUORO(METHYLCYCLOHEXANE)

Perfluoro(methylcyclohexane) is used as a solvent to determine fluorophilicity of hydrocarbon and fluorocarbon-functionalized nicotinic acid esters. It combines with chloroform and acts as an ingredient for "fluorous" biphase reactions. Furthermore, it finds application as a heat transfer agent, a dielectric fluid and a perfluorocarbon tracer. It acts as a good solvent for gases.

General Description

Mixtures of chloroform and perfluoro(methylcyclohexane) can be used as solvents for "fluorous" biphase reactions. Gas-phase structure of perfluoro(methylcyclohexane) was investigated.

Safety Profile

Mildly toxic by inhalation. When heated to decomposition it emits toxic fumes of Fí.

Purification Methods

Reflux it for 24hours with saturated acid KMnO4 (to oxidise and remove hydrocarbons), then neutralise, steam distil, dry with P2O5 and pass slowly through a column of dry silica gel. [Glew & Reeves J Phys Chem 60 615 1956.] It can also be purified by percolation through a 1metre neutral activated alumina column, and 1H-impurities are checked by NMR.
