HC-12a, also called ES-12a, OZ-12a, DURACOOL 12a [1] and Hydrocarbon Blend B, is marketed as a "drop-in" replacement refrigerant for R-12 and other refrigerants. HC-12a is a mixture of hydrocarbons , specifically propane (R-290) and isobutane (R-600a), and is therefore considered nearly non-ozone-depleting.
This basic scheme is modified as follows: Capital letters "B" and "I" are suffixed, together with atom counts, if chlorine atoms have been replaced with bromine or iodine . If there are two carbons, the isomer without suffix is the most symmetrical; after this, lower-case suffixed letters "a", "b", ..., are added, moving forwards through the ...
This paint scheme was used only for the races that were held during the length of the Olympic Games. [6] Charities. During the 2010 All-Star race at Charlotte Motor Speedway, Dale Earnhardt Jr. ran a special paint scheme featuring the JR Foundation Logo on the hood, to commemorate this occasion. The design was reintroduced for the 2012 All-Star ...
The refrigerant was developed by the DuPont/Honeywell company and is more expensive per pound than R-134a. R-1234yf can be found in late-model cars and is not cross-compatible with older R-134a or R-12 systems. Of the three refrigerants, R-1234yf is the best for the environment with the lowest global warming potential number which is about a three.

Mineral oil used with R-12 is not compatible with R-134a. Some oils designed for conversion to R-134a are advertised as compatible with residual R-12 mineral oil. Illegal replacements for R-12 include highly flammable hydrocarbon blends such as HC-12a , the flammability of which has caused injuries and deaths.
1,1,1,2-Tetrafluoroethane (also known as norflurane (), R-134a, Klea 134a, Freon 134a, Forane 134a, Genetron 134a, Green Gas, Florasol 134a, Suva 134a, HFA-134a, or HFC-134a) is a hydrofluorocarbon (HFC) and haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane) but with insignificant ozone depletion potential and a lower 100-year global warming ...
