Okay, I know there is a thread "NO, you can't make sodium" pinned on this forum, but I had this idea and I just think it might work.
So here's what we do:
Make the highest concentration possible of [latex]NaCl[/latex] in [latex]H_2O[/latex]. Then we add petroleum, as much as we used water in the first mixture. Petroleum is insoluble in water, it's boiling point is 150 °C and it should only be used to preserve the [latex]Na[/latex] from reacting once separated from [latex]NaCl[/latex]. Then we start heating the mixture while electrolysis takes place. Must be careful not to exceed 150 °C as petroleum will evaporate. So as [latex]Cl2[/latex] is formed and goes away, [latex]Na[/latex] will react with water all the way to a point where there is not enough water to react - when enough water is evaporated, there should remain some [latex]Na[/latex] after each reaction with water. [latex]NaOH[/latex] is at the same time electrolised and after all water is evaporated, [latex]Na[/latex] should remain protected in petroleum.
Just wanted to hear if this is possible.
