Here I will describe how to purify widely available ethyl acetate containing nail polish. It's usually called "acetone free nail polish", however don't confuse it with methyl ethyl ketone nail polish. Impurities can vary from country to country but these have usually greater boiling point than ethyl acetate and can be removed easily by distillation. Here fractional distillation would be ideal, collecting fraction of 72-78*C. But 1-2 distillations seem to be sufficient for most purposes, since there is a big difference between boiling points of impurities and ethyl acetate. It may be enough with one distillation if final product will be used in solvent applications. As example, one usual impurity can be butyl acetate (bp. 126,5*C). Other heavy oils are present too. These less volatile liquids suppose to keep skin moist when used in its primary purpose, but we don't care about this.. :) Distillation can be carried out in water-bath using homemade distiller. First distillation is stopped when no more liquid distils over. Second may proceed until there are small amount of liquid left (it may still contain lots of ethyl acetate, but also quite alot of impurities). Of course if you have a decent distilation setup with a thermometer, you can follow the temperature of distilate..
