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).
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.
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 ...
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. The perfluorinated amine will also be produced: N(C 6 H 13) 3 + 39 HF → N(C 6 F 13) 3 ...
[3] F-gases are ozone-friendly, enable energy efficiency, and are relatively safe for use by the public due to their low levels of toxicity and flammability. However, most F-gases have a high global warming potential (GWP), and some are nearly inert to removal by chemical processes.
Global warming potential (GWP) is a measure of how much heat a greenhouse gas traps in the atmosphere over a specific time period, relative to carbon dioxide (CO 2). [1]: 2232 It is expressed as a multiple of warming caused by the same mass of carbon dioxide (CO 2). Therefore, by definition CO 2 has a GWP of 1.
When mixed with O 2, CO 2, or N 2, in the range of reported applications, the GWP of the complete mixture is usually in the range of GWP 100 300-500. Additionally, the GWP is a CO 2 equivalent per unit of mass and C4-FN mixtures being typically 50% lighter than SF 6, the CO 2 reduction is in the range of 98.7-99.3% compared to SF 6 at identical ...
The gross world product (GWP), also known as gross world income (GWI), [1] is the combined gross national income (previously, the "gross national product") of all the countries in the world. Because imports and exports balance exactly when considering the whole world, this also equals the total global gross domestic product (GDP).
