11. Each series varied by degree of fluorination . 12. It is a strong fluorination reagent. 13. Is also used in the fluorination of aromatic compounds, although selective monofluorinations are more difficult: 14. Fluorination of dichlorophosphates can produce difluorophosphates.15. In electrochemical fluorination , butadiene sulfone can increase the yield of perfluorooctanesulfonyl fluoride by about 70 %. 16. Bigelow's primary field of research was fluorine chemistry and the direct fluorination of organic compounds. 17. :For non-bottle applications, fluorination of plastic can provide compliance with state and federal regulations. 18. Recent studies have also revealed that, similar to fluorination , full chlorination of graphene can be achieved. 19. For making niche organofluorines and fluorine-containing pharmaceuticals, direct fluorination is usually too hard to control. 20. One major advantage of radical fluorination is that it allows the direct fluorination of remote C H bonds.
