Would it be reasonable to assume that if one had a mixture of roughly 40mL nitroethane and 250mL heptane (which refused to seperate via fractional distillation, forming a smooth curve of azeotropes), that it could be extracted with 12M aq. NaOH, which could then be seperated and titrated with HCl to neutrality, at which point the nitroethane would precipitate from the water solution? Or would it be necessary to extract from the neutralized water solution with a different, easier to fractionally distill non-polar solvent (say, diethyl ether)?
