R134a is the replacement for R-12.
A product called freeze12 is a propane blend drop in replacement for R12, it should also work for replacement of R-134a.

Jeff explained how we need R-12, R-134a and propane blends to achieve certain pressures as they phase change.

Straight propane would be more like trying to replace R-22 or R-410a. If either one of these were used in an automotive A/C it would break something because the pressures would be way too high.
