Web• This is not often the case. Frequently some of the neutral organic material will be lost to the water layer, and sometimes some of the ionic material will go into the ether layer. In either case, either the yield and/or the purity will not be 100%. To improve extraction efficiency, often two (or more) extractions may be appropriate. WebIt is now soluble in water but insoluble in ether. At this point, the deprotonated organic salt would reside in the aqueous layer (Figure 1). in ether NH On naphthalene benzoic acid NaOH HO NH 00 Na in ether aniline in water Figurel.
