The propane that we burn in our ovens and furnaces is very impure with a lot of other things besides propane in it. The other things in it might have a very negative impact on your cooling system. The propane used in Duracool and such HC12a refrigerants is highly purified propane.
I would not consider trying to make my own, and I am a Chemical Engineer.
