Can someone please tell me the difference between HC12a and HC22a. I have googled my brains out and in fact I have not found any comparison between any home and auto refrigerant. I would love to know. I am not asking about opinions on hydrocarbon based products, I was asked the question in conversation and now I want to know.

134A is the replacement for R-12 in autos.
R410A is going to be the universal for commercial.residential rarther than R-22.

R-12A is a mixture of propane & butate. Both are flamable & if there is a leak, can go BOOM.
R-22A: The only thing I could find on "R-22A" was for something sold by Enviro-Safe as ES-22A. In the MSDS it's proper shipping name is "Petroleum Gas, Liquified" & it's shipping number is UN1075, the same as propane. It is listed as a flamable gas but it's chemical composition, I don't know.

Let me expand this a bit. What it the difference between auto refrigerant and home refrigerant ? I have been an auto tech for 23 years so I do understand the compensate make up of the hydrocarbon stuff. What I can't find is what's the diff from car to home?

The differences in refrigerant cause different temperatures/pressures. The reason for using the different refrigerants is load/air flow/dehumidification.
In a car you want a fast knock down of temperature & dehumidification is secondary. In a home, if you knocked down the temperature as rapidly as in a car, you would have moisture dripping off the walls.
Hope that answers your question.

Thank you, that does tell me why. I am sure some day I will get to the chemistry of it. I hope not but you never know. Thanx.
