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.
Fluorinert is the trademarked brand name for the line of electronics coolant liquids sold commercially by 3M.As perfluorinated compounds (PFCs), all Fluorinert variants have an extremely high global warming potential (GWP), [1] so should be used with caution (see below).
A further study, conducted by the Armines Centre energétique et procédés and by Energy Research Innovation Engineering (ERIE) found that emissions reductions of up to 60% can be achieved by improving containment measures and accelerating the changeover from high GWP refrigerants to ones with lower GWP.
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 ...
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
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).
Lexus again tops the ranks of J.D. Power’s newest vehicle dependability survey (VDS), but car owners overall are making more complaints as vehicles get more and more complex.
4 October 2019 At the 15th meeting of the United Nation's Stockholm Convention's Persistent Organic Pollutants Review Committee (POPRC-15) held in Rome, on 4 October, over 100 scientific experts representing many countries, "recommended that a group of hazardous chemicals"—"Perfluorohexane sulfonic acid (PFHxS), its salts, and PFHxS-related ...
