The partition coeffs. in the system 12:28:40 MeOH-2% HCl-CHCl3 of 9 PhCH2NHR.HCl after 96 transfers were (R, partition coefficient): H, 87.5; Me, 75.2; Et, 37.3; Pr (I), 12.3; Bu (II), 2.84; Am (III), 1.04; hexyl (IV), 0.3; heptyl (V), 0.084; octyl, 0.071. Pure III could be sepd. by this procedure in a mixt. of I, II, III, IV, and V whereas increased distributions were required for the quant. sepn. of the other 4 compds.
