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 −90 °C.
Liquid breathing is a form of respiration in which a normally air-breathing organism breathes an oxygen-rich liquid which is capable of CO 2 gas exchange (such as a perfluorocarbon). [ 1 ] The liquid involved requires certain physical properties, such as respiratory gas solubility, density, viscosity, vapor pressure and lipid solubility, which ...
Different molecular formulations are available with a variety of boiling points, allowing it to be used in "single-phase" applications, where it remains a liquid, or for "two-phase" applications, where the liquid boils to remove additional heat by evaporative cooling. An example of one of the compounds 3M uses is FC-72 (perfluorohexane, C 6 F 14).
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
Liquid ventilator can perform therapeutic lung lavage, the washout of endogenous and exogenous debris from the lungs, without suspension of ventilation support (without apnea). For example, literature data suggest a radical change in the treatment of meconium aspiration syndrome (MAS) by considering the use of a liquid ventilator. The ...
Perfluorohexanesulfonic acid (PFHxS) (conjugate base perfluorohexanesulfonate) is a synthetic chemical compound.It is one of many compounds collectively known as per- and polyfluoroalkyl substances (PFASs).
Perflubron has also been tested experimentally for use in liquid breathing in premature infants with respiratory distress. [3] [4]This molecular model of Perflubron is color-coded by electron density to illustrate the positive polarisation of the large bromine atom by the inductively electron-withdrawing perfluorooctyl chain.
Fluorosurfactants (PFAS) reduce surface tension by concentrating at the liquid-air interface due to the lipophobicity of polyfluorocarbons. Chlorofluorocarbons are also perfluorinated compounds, many of which were formerly used as refrigerants ( Freon ) until they were implicated in ozone degradation .
