The combustion experiment was also conducted at different amounts of excess oxygen (5 to 40%) and different flow rates (700 to 1,100 L/h). At 20% excess oxygen and a flow rate of 860 L/h, the amount of fluorine emitted ranged from 850.7 ng/kg at 950 °C to 3,632.8 ng/kg at...
A second chemical property of alkanes is halogenation. Halogenation is a chemical reaction used to add a halogen to a compound. Halogens consist of five elements that are chemically related to one another: fluorine, chlorine, bromine, iodine, and astatine. Lesson...
As antiviral nucleosides containing a 2',3'-unsaturated sugar moiety with 2'-fluoro substitution are endowed with increased stabilization of the glycosyl bond, it was of interest to investigate the influence of the fluorine atom at the 3... Y Chong,G Gumina,JS Mathew,... - 《Journal of Me...

A review of literature related to the process of fluorination of uranium dioxide and physical properties of the compounds involved (uranium hexafluoride, fluorine, uranium dioxide and argon) is presented. It is pointed out that there exist strong indications that the maximum rate of fluorination of ...
