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).
Total liquid ventilation, however, has difficulty moving enough liquid to carry away CO 2, because no matter how great the total pressure is, the amount of partial CO 2 gas pressure available to dissolve CO 2 into the breathing liquid can never be much more than the pressure at which CO 2 exists in the blood (about 40 mm of mercury ).

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 ...
A water sample is measured as part of a PFAS drinking water treatment experiment, Tuesday, Feb. 14, 2023, at the U.S. Environmental Protection Agency Center For Environmental Solutions and ...
Volatile anaesthetic agents share the property of being liquid at room temperature, but evaporating easily for administration by inhalation. The volatile anesthetics used in the developed world today include: Desflurane, isoflurane and sevoflurane. Other agents widely used in the past include ether, chloroform, enflurane, halothane, methoxyflurane.
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).
Perfluoroalkanes are very stable because of the strength of the carbon–fluorine bond, one of the strongest in organic chemistry. [4] Its strength is a result of the electronegativity of fluorine imparting partial ionic character through partial charges on the carbon and fluorine atoms, which shorten and strengthen the bond (compared to carbon-hydrogen bonds) through favorable covalent ...
Solubility is the property of a gas, liquid or solid substance (the solute) to be held homogeneously dispersed as molecules or ions in a liquid or solid medium (the solvent). In decompression theory, the solubility of gases in liquids is of primary importance, as it is the formation of bubbles from these gases that causes decompression sickness.
