Methly Acetate Propandine Stabilized
Which is just methane and propane? propane is already a great refrigerant, but methane is better(i think). So wouldnt this be better than propane and still easily available?

Geez.
methyl acetate =! methane =! methyl acetylene
propadiene =! propane
MAPP = methyl acetylene propadiene
Mind the spelling. Every letter in organic chemistry means something.
Methyl acetate is the reeking stuff from fingernail polish remover.
Propadiene I don't know much about.
I've heard reports MAPP destroys copper, but nothing verified.

At least it won't kill the **** out of you. OSHA PEL (Personnel exposure limit) is 1000 ppm, so you're probably safe with it if you use some common sense - well-ventilated area, some sort of facial protection, etc.
This has been your engineering safety brief.
