It is shown that the distribution of homologous series of nor-α-aminoacids in liquid two-phase three-component systems formed by salting-out of low aliphatic alcohols from their aqueous solutions by sodium chloride can be described by the following relation: 6nZ)=a + blnφ, where:Dis the distribution coefficient expressed as the ratio of concentration of aminoacid in the upper and lower phases, respectively; φ is the ratio of alcohol concentration expressed in molar percent in the same phases; a and b are constants related to activity coefficients and salting-out constants of aminoacid and alcohol by sodium chloride.
