Perfluorocyclohexane or dodecafluorocyclohexane is a chemical which belongs to the class of fluorocarbons, sometimes referred to as perfluorocarbons or PFCs. Fluorocarbons and their derivatives are useful

fluoropolymers A fluoropolymer is a fluorocarbon-based polymer with multiple carbon–fluorine bonds. It is characterized by a high resistance to solvents, acids, and bases. The best known fluoropolymer is polytetrafluoroethylene under the brand name "Tefl ...

refrigerants A refrigerant is a working fluid used in the refrigeration cycle of air conditioning systems and heat pumps where in most cases they undergo a repeated phase transition from a liquid to a gas and back again. Refrigerants are heavily regulated ...

solvents A solvent (s) (from the Latin '' solvō'', "loosen, untie, solve") is a substance that dissolves a solute, resulting in a solution. A solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid. Water is a solvent for ...

anesthetics An anesthetic (American English) or anaesthetic (British English; see spelling differences) is a drug used to induce anesthesia ⁠— ⁠in other words, to result in a temporary loss of sensation or awareness. They may be divided into two ...

Synthesis

Perfluorocyclohexane can be synthesized by fluorination of cyclohexane.

Properties

Perfluorocyclohexane is chemically inert and thermally stable. It is a relatively non-toxic, clear, waxy solid, which has a high

vapor pressure Vapor pressure (or vapour pressure in English-speaking countries other than the US; see spelling differences) or equilibrium vapor pressure is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phase ...

and therefore sublimes readily at room temperature. In common with other cyclic perfluorocarbons, perfluoromethylcyclohexane can be detected at extremely low concentrations, making it ideal as a tracer. The molecule predominantly exists in its chair conformation, in which it possesses D_3d

molecular symmetry Molecular symmetry in chemistry describes the symmetry present in molecules and the classification of these molecules according to their symmetry. Molecular symmetry is a fundamental concept in chemistry, as it can be used to predict or explain ...
