I love to stimulate conversation and this sounded like a good topic to do so. This is not fiction just chemistry. Alcohol by nature is hydroscopic, meaning it readily absorbs into other liquids, gas as well as water. The Alcohol is more hydroscopic to water than to petroleum products. A cool experiment for you to try for yourself to see this is to take a clear soda bottle. Poor about 2 cups of water in the bottle, the amount is not critical. Use a permanent marker and mark the water level, then fill it about half full with gas, cap it and shake it for a minute or so. The idea here is to get as many water molecules in contact with as many gas molicules as you can. The next step is just waiting. The process doesnt happen immediately, it takes a while. I normally let it sit over night. After the water has settled take a look at much higher the water level is, that is now the water plus the alcohol it has absorbed. For you purest if you measure how much water you used and how much gas you used you can see the percentage of alcohol that was removed. I normally get between 8 and 10%. The next trick is figuring out how you want to separate it, this can be accomplished in several ways. Regardless how I separate it the last step I use is to strain the gas through a Mr. Funnel (http://www.mrfunnel.com/Mr._Funnel/Home.html ) This is an add so only watch it if you want to. Mr Funnel is a water separator filter that work very well. :blob:
