       methylisobutylketone in EtOH?     

to rectified EtOH there is added metylisobutylketone, i wonder if someone might knew a way to get rid of this? Could i just add bisulphite?? I have tried a method witch involve sulphuric acid and regular food oil, and got a white precipitate. what happens here? is it the triglyceride in the oil that goes over to fatty acid and then kombine with the EtOH in an esterification or could the oil combine with the ketone??

       Aldolcondensation     

Reflux your EtOH (or eaven bether us an soxhlet) with BaOH(best) or KOH or NaOH. Then all the ketone condensate into blac tar witch can bee left behind an destilation
