Comparison of n-Dodecane/Brij 30/water and n-Decane/Brij 30/water nano-emulsions produced by PIT method
No full textIn this study, nano-emulsions were prepared using 19.2 wt% n-Dodecane (C12H26) and n-Decane (C10H22) oils as the dispersed phases, 4 wt% Brij 30 (C12E4) as surfactant and 76.8 wt% ultrapure water as the aqueous phase by phase inversion temperature (PIT) method. PIT points were determined by measuring the conductivity of the mixture as a function of temperature. The stability of nano-emulsions was determined by measuring the mean size, polydispersity index (PDI) and size distribution of droplets using dynamic light scattering (DLS) technique and monitoring them as a function of time. The nano-emulsions were also characterised using refractive index (RI), surface tension and pH measurements. The efficiency of reversibility test was also investigated on systems aged for various durations (i.e. 3, 4, 5, 9 and 470 days). Experimental results show that n-Dodecane system has higher conductivity values than n-Decane system and as a consequence the PIT values for n-Dodecane system were found to be higher than those for n-Decane system. All freshly produced nanoemulsions were found to be similar in appearance being opaque white with opal shine. But they were found to lose the shine and became duller with ageing. n-Dodecane systems seem to produce less stable nano-emulsions than n-Decane systems. They were also found to have larger droplets and higher RI values but mostly lower pH compared to n-Decane systems. Surface tension values for the reversed n-Decane system were found to be lower when compared to those for fresh one. Both n-Decane and n- Dodecane systems lead to an increase in droplet size over the study period of 3 days. Also, the variations in PDI and size distribution of droplets over the study period are significant in this work.Firoozeh Pourjavaheri-Jad, Rajarathinam Parthasarathy, Nhol Kao and Yung Ngotha

Effects of NaCI and KCI concentrations on oil/water nano-emulsions produced by PIT method
No full textThe present work investigates the effects of NaCl and KCl salt concentrations in the ranges of 0 to 1.0 M on n-Dodecane-in-water/brine nano-emulsions produced by phase inversion temperature (PIT) method. PIT points of the oil/brine solutions were found using conductivity measurements. The stability of the nano-emulsions was determined by measuring the mean size, size distribution and polydispersity index of droplets using dynamic light scattering technique and monitoring them as a function of time. The results showed that both NaCl and KCl salts depress the PIT points. However, the system without salt produces the most stable nano-emulsions. The system containing KCl solution shows lower droplets growth rate at low salt concentrations and higher droplets growth rate at high salt concentrations as compared with those for NaCl system within the 3 days ageing period used in this study. Also the variations in the size and size distribution of droplets with change in salt concentration are significant within the salt concentration range used in this study.Firoozeh Pourjavaheri-Jad, Rajarathinam Parthasarathy, Nhol Kao, Yung Ngothai and Jeffery Liewhttp://www.chemeca2010.com/abstract/264.as
