Can anyone help me to give solution for seperation of acetone+tetrahydrofuran (THF)mixture?
Feed composition :
Acetone :80%
THF:10%
water :10%
Required purity
Acetone :Not less than 99%
THF:Not less than 0.1%
Water : Not less than 1%

Regards,
Bhaskaran

Dear Bhaskaran,

If I correct your final product requirements to: Not more then 0.1% THF; Not more then 1% Water,
I think the most effective would be:
   

Do first a “Thin-film-Short-way”-Distillation (Maybe twice)
and then dry the product with a usual chemical if still required.
   (Bp:  Aceton  56.7° Celsius;  THF   65.8° Celsius; that should be much more then enough.)

Good Luck!

Sir,
Can u explain what is “Thin-film-Short-way”-Distillation ?

Note:
Acetone & THF forms azeotrope.

Iam not clear whether u can able to seperate this y distillation.

Please clarify.

Dear Bhaskaran,

Thank you for the hint of the Azeotrope.
I didn’t find it in my quite (but not enough) large Data Base (DB), and so I though an effective Distillation must do it.
(Would you be so kind to spend my DB the azeotropic data of this mixture?)

In case of this Aceotrope and my opinion I would try a “Swing-Distillation”, depending on the volume you have. It makes most sense to me.
I don’t know if in such a try a “Thin-film-Short-way”-Distillation is required or indicated.

About “Swing-Distillation”,  you can read under the headline:
“Aceotrope Breaking” (“Separation of aceotrope constituents”) on:

"Azeotrope”

Of course, other methods of “Aceotrope Breaking” are also discussed therein. It’s at least a collection of Ideas.

Apropos: “Thin-film-Short-way”-Distillation:
I’m searching for an English paper version, because I have it “only” in German.

Good Luck!

its a azeotrope of 92% acetone and 18% thf
