Subject:A few comments on ethanol, was Re: R134 conversion

Grain alcohol is 190 proof, or 95% ethanol.  The other 5% is water.  The
only ethanol that doesn't have any water is 200 proof.  I believe you
can buy it in some FLAPS by different brand names, used for drying out
wet gas.  Having said that, all ethanol mixes readily with water; the
higher the proof, the more it can absorb, but grain alcohol would work
in a pinch.  You might prefer to drink it though . . .  :^)  Ethanol
will absorb water readily and not release it unless you boil off the
ethanol (180 degrees F) or run it through some kind of dessicant.  The
only feasible way to get rid of that last 5%, going from 190 proof to
200 proof, is by running it through a good, dry dessicant.
