A base-base extraction was done using 0.4g of a mixed compound at ratio 1:2:1 of benzoic acid, 2-napthol, napthalene that was dissolved in diethyl ether.  NaHCO3 was added, shaken, and then separated off using a funnel and saved.  Cold NaOH was added, shaken, funneled off, and then saved.  The remaining organic layer was then funneled off, saved, and dryed.  The NaHCO3 and NaOH fractions were made acidic with additions of HCl, then vacuum dried via buchner funnel.  Neutral fraction was dryed via reduced pressure.  All samples were then weighed for recovery and melting points were measured.  What modifications if any would have to be done to the procedure if the experiment were repeated using dichloromethane instead of diethylether?  Which parts would be affected and why?
