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 ...
Data from the 2003-2004 National Health and Nutrition Examination Survey in the United States found the average serum concentration of PFHxS in the general US population to be 1.9 μg/L, with the 10th and 90th percentiles being 0.7 and 8.3 μg/L, respectively. Some studies reported serum PFHxS concentrations in the United States to be gradually ...
As perfluorinated compounds (PFCs), all Fluorinert variants have an extremely high global warming potential (GWP), [1] so should be used with caution (see below). It is an electrically insulating, stable fluorocarbon-based fluid, which is used in various cooling applications. It is mainly used for cooling electronics.
Perfluorohexanoic acid (PFHxA) is a fluorinated carboxylic acid derivative of hexanoic acid.Fluorinated polymers with six carbon or less commonly degrade into perfluorohexanoic acid.
Public water systems in New Jersey are required to meet an MCL standard of 13 ppt. [186] [187] In 2020 the state set a PFOA standard at 14 ppt and a PFOS standard at 13 ppt. [188] In 2019 NJDEP filed lawsuits against the owners of two plants that had manufactured PFASs, and two plants that were cited for water pollution from other chemicals.
A 2018 report to Congress indicated that "at least 126 drinking water systems on or near military bases" were contaminated with PFAS compounds. [8] [9] A 2016 study found unsafe [10] levels of fluorosurfactants in 194 out of 4,864 water supplies in 33 U.S. states. Covering two-thirds of drinking water supplies in the United States, the study ...
2,2-Dichloro-1,1,1-trifluoroethane can be produced by reacting tetrachloroethylene with hydrogen fluoride in the gas phase. This is an exothermic reaction and requires a catalyst: This is an exothermic reaction and requires a catalyst:
