Du Pont, the major manufacturer of CFCs, gave their own products the brand name Freons, and developed a labeling system that indicates, to the cognoscenti, how many atoms of each kind are present in a particular type of Freon. This system is now widely used for all CFCs; a shorthand naming system has evolved in which the two most commonly used CFCs are known as F-11 and F-12 - their full chemical names are trichlorofluoromethane (CC13F) and dichlorofluoromethane (CC12F2). 1, record 2, English, - shorthand%20naming%20system

Les halons étant très nombreux, les chimistes américains, qui les ont particulièrement étudiés, ont aussi fixé les règles de leur nomenclature. Leur formule chimique est représentée par un nombre de quatre chiffres : le premier indique le nombre d'atomes de carbone de la molécule; le deuxième, de fluor; le troisième, de chlore : et le quatrième, de brome. 2, record 2, French, - nomenclature%20industrielle%20abr%C3%A9g%C3%A9e
