R-13b1 CFC: No; banned by Montreal Protocol: Low temperature refrigerant-40 to -60°C.

The main difference between the two types of refrigerant is that HCFCs contain one additional hydrogen atom compared to CFCs. values provided here from the AR5 for non-CO2 gases do not include climate-carbon feedbacks. Global warming potential CFC-12 CCl2F2 8,100 10,900 10,200 In 1928 Thomas Midgley Jr. created the first non-flammable, non-toxic chlorofluorocarbon gas, Freon (R-12). The name is a trademark name owned by DuPont (now Chemours) for any chlorofluorocarbon (CFC), hydrochlorofluorocarbon (HCFC), or hydrofluorocarbon (HFC) refrigerant. At the moment the effect is still small -- about 0.012 W/m 2 for all CFC substitutes combined. But it is beyond question that radiative forcing due to HFCs will rise significantly in future as a gases have 100-year global warming potentials (GWPs), which are typically greater than 1,000 times that of CO 2, so their potential impact on climate change can be significant (see examples in Table 1). By the same token, any reductions of these gases can have a large potential benefit.

Some of these compounds, especially trichlorofluoromethane (CFC-11) and dichlorodifluoromethane (CFC-12), found use as aerosol-spray propellants, solvents, and foam-blowing agents. They are well suited for these and other applications because they are nontoxic and nonflammable and can be readily converted from a liquid to a gas and vice versa.
