True, I meant the ~100F to read "about 100F", so as to point out it is in the ballpark with Pentane at 36.1C/97F.

Dimethyl ether, is based on the ethane molecule split in half with and oxygen molecule, leaving one methyl leg on either side and is also relatively non toxic.
It should be easier to purge than butane, but is more water soluble.
It's not, though. DME (Dimethyl Ether) is what is in the can of MZ12X.
And has a boiling point of -11F
DEE (Diethyl Ether) is not whats in the can and has a BP of 94F
