How to Seperate a same boiling point mixture.

[naapranam]

hi
can any tell me how to seperate a same boiling point mixutre. i would like to seperate Isopropyl Alcohol (90%w/w) and Acetonitrile(10% w/w). Iso Propyl alcohol -82.6 C (BP) and Acetonitrile - 81.6 C(BP)...is there any method to seperate this mixture...or any general method to seperate the solvents of Same Boiling point.

Generally close boiling comp mixs are isomers . But IPA and acetonitrile are not. Thus you can use: Extractive distillation, azeotropic distillation, just extraction followd by distillation, membranes.
I am sure ED should work here google for IPA-acetonitrile-extractive dist...

thank you...plz upload if you have any good material on extractive distillation...

you can´t do it, you need first separate with solvent in one absortion one and then distillation o desorption in the next pass.
