1. Special nomenclature
Fluoroalkanes are more or less fluorinated derivatives of the corresponding chloroalkanes (mainly chloroethanes and chloromethanes).
They are generally designated by the letter R (for "refrigerant"), sometimes by the letter F (for "fluorocarbon"), followed by a code number obtained in the following way:
the units correspond to the number of fluorine atoms in the molecule;
the tens digit corresponds to the number of hydrogen atoms plus one;
the hundreds digit corresponds to the number of carbon atoms minus one.
R22 designates difluorochloromethane or CHClF 2 .
These rules are supplemented...

Producers
Regulatory changes have seriously affected all producers in their development strategies for these products; moreover, a large proportion of CFC substitution is taking place with non-fluorinated products: as can be seen in figure 1 , tonnages produced...
