Can I replace R12 with r600?
R600a is a good replacement
for R12
However its smaller volumetric capacity and higher pressure ratios, limit it to very small capacities. With regard to R600a, it has a lower molecular weight, 58.1 kg/kmol in comparison to R134a, 102 kg/kmol, which results in a lower charge for Isobutane.
Why did they get rid of R12?

What refrigerant is replacing R134a?
To date, most auto manufacturers are using the
hydrofluoroolefin (HFO) refrigerant R-1234yf
as the replacement of choice for R134a. The 2013 Cadillac XTS was the first U.S.made vehicle to use the new refrigerant. With a GWP of 4 (instead of 1,430 for R-134a) R-1234yf is more environmentally friendly.
Is R134a refrigerant being replaced?
Honeywell’s HFO1234yf refrigerant
has been developed as a replace- ment for R134a, and has already proven its effectiveness in several bench tests and field tests in terms of energy efficiency, environmental benefits, safety, performance and ease of adoption.
