Abstract Barium ethyl(octyl)phosphate (EOP), ((C2H5O)(C8H17O)PO 2 − )2Ba2+, was synthesized and the phase diagram of the EOP-water system consisting of four regions (I, II, III, and IV) was determined. The phase structure was studied from the self-diffusion coefficients obtained by the1H pulsed-gradient NMR method. In region I, a critical micelle concentration (CMC) was found, indicating the presence of a monomer ⇆ micelle equilibrium. Region II is a two-phase area in which regions I and III coexist. For region III, the structure of the aggregate system was found to depend upon the concentration.
