Water and n-butanol are immiscible. In this paper, i-propanol was found to be surface active for both water and n-butanol using surface tension measurement at 25.0±0.1°C, especially the system with i-propanol in water displays a pronounced decrease in surface tension with a distinct inflexion point indicating aggregation. Investigation on phase behavior of water/i-propanol/n-butanol ternary system at 25.0±0.1°C showed i-propanol could promote remarkably the miscibility of water and n-butanol. Cyclic voltammetric technique was employed to locate the micro-regions in single region, indicating the existence of three micro-regions of water/n-butanol, n-butanol/water and bicontinuous region. Thus, a novel water/i-propanol/n-butanol microemulsion without general surfactant is expected to form. Dynamic light scattering also demonstrated the size (hydrodynamic diameter) distribution of the microemulsion, verifying further the formation of the microemulsion droplets. |
