is it possible to evaporate alcohol like vadka (40%) to lets say a higher % of alcohol like 80 by evapoting half is volume?
i belive alcohol will evap before water will so im not sure how i could get the water to evap while leaving the alcohol in its liquid concentrated form?
are there any ways to do this?

Just like making moonshine. You would have to evaporate the alcohol off using controlled heat, leaving most of the water behind. Catch the alcohol vapors in a condenser and turn it back into a liquid.

Yes the process is called distillation. Actually the alcohol is evaporated and condensed in a cooled tube leaving the water behind. The alcohol that distills or comes across has a maximum concentration of about 90% (180 proof). The reason that it is not 100% is that some water comes with it as an azeotrope. There are ways to make absolute alcohol but it involves adding another compound to the distilling mixture. See more about azeotropes in your chem book.

Yes, there is. It's called distillation- where the current alcohol, like Vodka, Scotch, Rum from various fermented wheat grains and other things (like Juniper in Gin) and others are heated in a special vat that causes them to evaporate and catch the higher concentrated alcohol into another vat. However, I believe that you need a special license to do this; otherwise, it's considered illegal in Canada and the US. As far as I know, it's illegal, without a license to even make anything over 20 proof (the point where the alcohol starts to kill the yeast)- like those used in making sherry.

Water freezes before alcohol, so you could try to freeze the water and remove the ice, thereby giving you a higher alcohol concentration! But... you would probably freeze all of the water leaving only pure alcohol in solution. You can do this and take the pure alcohol you get and then add the pure alcohol to another bottle of vodka.
Hope this helps...

Another thing you might find intresting is that you can only distill to a certain percentage around 95%, 100% ethanol is unstable and will absorb water from the air to become around 95% without an additive to prevent that. welllll if you are actually going to try distillation dont forget your boiling chips!
