well scott i tried to do some research but came up with nothing. i did see a site that said the freezing point of rubbing alcohol is around -88 C. what was your technique in trying to freeze it. im not really all that familiar on how alcohol reacts with water, but from other things i've read it acts the same as 'salt' does whenever applied to roads in the north. it either lowers the freezing point. therefore im guessing that the alcohol is acting as though it is dissolved and therefore you might not be able to freeze of the water. i dont know for sure though. i know that alcohol has a lower boiling point than water so that would always be an option to consider....but remember alcohol is very flammable. try some searches on distilling alcohol or purification on alcohol and see if you can get anything.
