When looking at the properties of ethanol via the "properties" tab or via the database the documented thermal conductivity is 1.000. However I have a hard time believing this is true as this is the same thermal conductivity of gaseous metals in the game.
Steps to Reproduce
Simply look at the documentation in either the database or "properties" tab for gaseous ethanol and view the thermal conductivity.
This issue has been fixed in either a future version or updated in a previous version.
