This company sells 'R-22a', which I understand is an HC blend that is meant to be a drop-in replacement for R-22.
I haven't been able yet to verify exactly what the blend is, or what the water vapor allowed is.
They do have a non-sulphurous scent (like pine trees) that is added.
I got some for my next unit.
[EDIT:] I was just checking around on the web and on this page I found this quote:

This got me wondering, what is ES 22A? After a bit of googling about I found the MS/DS for ES 22A. Here are the specs from the MS/DS sheet converted to celsius.
ES 22A Specs
-42.5c boiling point
0.5066 Specific gravity
467c Auto ignition temp
Propane/R290 Specs
-42.1c boiling point
0.509 Specific gravity
470c Auto ignition temp
The slight differences can be accounted for by barometric pressure and purity of the gas tested.

[END OF EDIT]
The stuff sure ain't cheap, compared to BQ gas, but at $27/kg, it's better than $50/kg.
Note that they are going at this as a drop-in replacement for R-22, and the contents of a "30 pound" tank actually weighs 12 pounds. To me this seems deceptive, so be forewarned.
If we had a method that was dialed in for removal of water and any other potentially corrosive agents, and that could be implemented by a vapor-compression hobbyist, we would be making a major contribution to our community.
