Perfluorohexane (C 6 F 14), or tetradecafluorohexane, is a fluorocarbon. It is a derivative of hexane in which all the hydrogen atoms are replaced by fluorine atoms. It is used in one formulation of the electronic cooling liquid/insulator Fluorinert for low-temperature applications due to its low boiling point of 56 °C and freezing point of ...
Net global warming potential, GWP, over a 100-year time horizon (normalized to be 1 for R-744, carbon dioxide) Occupational exposure limit/permissible exposure limit in parts per million (volume per volume) over a time-weighted average (TWA) concentration for a normal eight-hour work day and a 40-hour work week
Perfluorohexane is used for low-temperature heat-transfer applications due to its 56 °C (133 °F) boiling point. Another example is FC-75 , perfluoro(2-butyl-tetrahydrofurane). There are 3M fluids that can handle up to 215 °C (419 °F), such as FC-70 ( perfluorotripentylamine ).
For example, refrigeration and air conditioning systems are increasingly utilized by humans within a warming environment. [4] Likewise, expansions of electrical infrastructure, as driven by the alternatives to fossil fuels, has led to rising demand for SF 6 . [ 5 ]
Carbon dioxide sees extensive use in large-scale refrigeration systems, sometimes via a cascade refrigeration system. [16] It is also used sparingly in automotive refrigeration, [ 20 ] and is seen as favorable for uses in domestic, commercial and industrial refrigeration and air conditioning systems. [ 1 ]
The process proceeds at low voltage (5 – 6 V) so that free fluorine is not liberated. The choice of substrate is restricted as ideally it should be soluble in hydrogen fluoride. Ethers and tertiary amines are typically employed. To make perfluorohexane, trihexylamine is used, for example: N(C 6 H 13) 3 + 45 HF → 3 C 6 F 14 + NF 3 + 42 H 2
