AB  - Mikroemulzije na bazi vode, toluena i nejonskih površinski aktivnih supstanci su interesantni za primenu, zahvaljujući izvanrednim karakteristikama aromatičnih ugljovodonika kao rastvarača.

AB  - Microemulsion systems with water, toluene and nonionic surfactants are interesting for application due to the excellent solvent properties of aromatic hydrocarbons. In this study, the pseudo-binary phase diagram ('fish-diagram') of such a ternary system was investigated using a branched technical alkyl polyethoxylate. Lutensol ON 50 (i-C10E5) was considered a suitable surfactant. The system with technical branched i-C10E5 exhibits very long, and for compositions near optimum solubilization, i.e., the minimum content of surfactant needed for a bicontinuous microemulsion, extremely long times for equilibration. In addition to visual observation, qualitative measurements of turbidity were performed with a UV-Vis spectrometer for characterizing the behavior of this unusually sluggish system. Isothermal phase diagrams at 20, 25 and 30°C yielded inconsistent results after the change of temperature and the application of mechanical stress for different treatment of the samples. Ternary mixtures of water, toluene, and lutensol ON 50 seem to form long-living metastable states. The sluggishness and the ambiguous phase behavior of the system are discussed. Inconsistent results are attributed to the slow kinetics of the formation and destruction of liquid crystals and the ability of the system to form mini-emulsions within an unusual concentration range.

AB  - Microemulsion polymerization is widely used as a cleaner alternative way to prepare intrinsically conductive polymers. We studied isothermal phase diagrams for microemulsions of the electropolymerizable heterocyclic aromatic oil 3,4-ethylenedioxythiophene (EDOT), aqueous LiClO(4) solution and alkyl polyethoxylate. Our specific goal was to assess the effect of LiClO(4) salt on the phase behaviour. The phase behaviour. was characterized by stepwise titration and microscopic analyses. Here we found that the increase of the concentration of LiClO(4) salt shifts the microemulsion region to lower surfactant content.
