The European Union agreed in February 2013 to the mutual procedures for the complete denaturing of alcohol: Per hectolitre (100 L) of absolute ethanol: 3 litres of isopropyl alcohol (IPA), 3 litres of methyl ethyl ketone (MEK) and 1 gram denatonium benzoate.
Distillation is almost certainly illegal.
You really need to get your lab connected to a business or educational facility. Here in the USA, there are chemical suppliers such as Sigma-Aldrich, that will sell just about everything, but I'm not sure if they ship to individuals. It looks like there is also an Italian branch. They do sell lab grade solvents, but I don't know how taxes affect the prices. It is likely that isopropanol or methanol will substitute for many uses of ethanol. at least as a solvent, not necessarily as a reactant.
