WebI think the idea is to separate the three layers into three separate flasks, and using NaOH at the start would just result in a mixture of acetic acid and phenol. By using two base strengths, you can have specific flasks for each compound. Comment ( 1 vote) 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.
