Methanol uses or methyl alcohol
Find wide use as:
Solvent (e.g. for the dilution of paints and in the polishing of furniture);
Reagent in industrial chemical processes;
Fuel (e.g. used in NASCAR, Indy Racing League and dynamic modelling mixed with castor oil or synthetic base plus a small percentage of nitromethane).
As a main component (60%) of the Methacarn (an alcoholic fixative liquid).
Used illegally, because highly toxic, to sophisticate the wine.
In Iceland it is also used as a means of storage for geothermal electricity, summarizing it starting from hydrogen obtained by hydrolysis and carbon dioxide.
