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.
