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.
The half-life of PFHxS in adult blood serum is 5.3 years (4.7 years for women and 7.4 years for men). [10] The half-life of PFASs in human blood generally decreases with decreasing backbone (CF 2) length. However, PFHxS is an unusual exception in that its half-life is greater than both longer and shorter chain equivalents such as PFOS or PFBS. [10]
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).
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 ...
For example, methane has a GWP over 20 years (GWP-20) of 81.2 [2] meaning that, a leak of a tonne of methane is equivalent to emitting 81.2 tonnes of carbon dioxide measured over 20 years. As methane has a much shorter atmospheric lifetime than carbon dioxide, its GWP is much less over longer time periods, with a GWP-100 of 27.9 and a GWP-500 ...
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 ...
Business ethics (also known as corporate ethics) is a form of applied ethics or professional ethics, that examines ethical principles and moral or ethical problems ...
In business ethics, Ethical decision-making is the study of the process of making decisions that engender trust, and thus indicate responsibility, fairness and caring to an individual. To be ethical, one has to demonstrate respect, and responsibility. [ 1 ]
