WebThe aqueous phase of a biphasic solvent system may be modified by the addition of a water-soluble salt, acid, or base. For example, one of the very first applications of CCC separation was the separation of amino acids by a solvent system consisting of chloroform, acetic acid and 0.1 M aqueous HCl in a 2:2:1 ratio. WebWater (BEW) 4:1:2.2 as the solvent system compared with Butanol-Acetic acid-Water (4:1:5) or in Butanol-Acetic acid-Ether-Water (BAEW) 9:6:3:1 because of the solvent systems polarity. Thus BEW (4:1:2.2) is less polar than BAW (4:1:5). The solvent systems used in the order of increasing polarity are as
