Is there a chemical that can substitue for ammonia gas?

Question

Here is my dilemma...

I was trying to use ammonia as an eco friendly refrigerant. Turns out it has a lot of issues.

1- It's corrosive to all metals with the exception of stainless steel. Fine! I'll use expensive stainless steel pipes.

2- It's used in the manufacturing of explosives! Crap! I can't use it. The Egyptian government is doing its best to prevent terrorists from getting what they need to manufacture explosives. So, they prevent average Alfred Q. Publics, like myself, from getting it.

Ammonia gas is highly soluble in water. It can also be absorbed by calcium chloride. It has a very low boiling point -33 Celcius. It is extremely corrosive. It is used in explosives.

Does anything exist that is either soluble in water or absorbed by some kind of salt and has a very low boiling point?

I'd prefer nothing corrosive.

But I sure DON'T want anything that can be used in explosives. Not even theoretically. :o)

Thanks a lot.

Well, welcome to the 19th Century. How about one of the current freon-replacement products?
