Why is it better to perform simple distillation for purifying isoamyl acetate?

Hi! When purifying isoamyl acetate, why is it better to perform simple distillation rather than fractional distillation?

Who said that it was?  Can you think of any reasons?

Based on different syntheses that I have read, they all performed simple distillation. I was thinking because it takes less time. Do you think we should perform fractional distillation instead? This is only for school's laboratory work.

Whether to use simple or fractional distillation depends on the identity of the other substance and the relative boiling points of the product and the other liquid.  If something takes less time, that is a good reason to use it, all else held equal.
