I have bought a bottle of denatured alcohol. On the web I've found these solutions typically contain the following:

  • $85\%$ ethanol
  • $10\%$ water
  • $3\%$ methanol
  • $1\%$ aceton
  • $1\%$ pyridine

I would like to get rid of the acetone. How can I remove it? (and how do I know if it is in my solution?)

    $\begingroup$ You should be able to distill the acetone and methanol off. $\endgroup$

    $\begingroup$ @Beerhunter I live in the Netherlands, 1 liter distillation devices are legal. I'm not concerned about the methanol, just the aceton since it's not good for my printed circuitboards. $\endgroup$ Feb 18 '16 at 16:00
