Subclass of itself?[edit]
This item is subclass of itself. That property should be removed or changed to a superclass. --Spischot (talk) 17:07, 20 April 2013 (UTC)
- No it isn't (at least it isn't now). it is a subclass of alcohols (Q156) which is an item for the class of all alcohols. Filceolaire (talk) 15:49, 14 April 2014 (UTC)
Item both subclass and instance?[edit]
Both subclass of and instance of properties are set for this (showcase) item. But ethanol is a single concrete alcohol and is not a class. There is only one ethanol, with a single chemical formula and structure. Only the instance of property is right for this item. Or I am wrong? Cuvwb (talk) 19:41, 14 July 2014 (UTC)

Specific Heat Capacity[edit]
I'm not expert, but ethanol specific heat capacity seem to be a serious error. Low by an order of magnitude. ~~
