The purity of the chemical being distilled. The higher the purity, the narrower the boiling point range. Keeping the entire distillation column at the same temperature as the boiling point of the pure chemical will let you pull a constent flow of pure chemical after the lower boiling point impuities have boiled off. A sudden change of temperature indicates your sample has all boiled off. All of this is possible only if you do not have mixtures which cannot be separated by fractioning.

Temperature of evaporation. It is a process used for seperating out the components of crude oil. At different levels of the fractionation column there are different temperatures at which different components of the crude oil condense and are drawn off on trays which are piped out of the column. Check out www.wikipedia.org , lots of info there.

Differences in boiling points.
As long as the boiling points are reasonably different.
