Abstract:

The experiments show that the middle phase microemulsions can form in tetradecane pyridinium bromide/alcohol/n-heptane/brine systems. The phase behaviour was investigated by using concentration scanning and interfacial tension methods. The formation and characteristics of the middle phase microemulsions are affected obviously by the concentrations of TPB from 0.5 % to 6.0 %, the concentrations of n-butanol from 2.0 to 7.0 % and the n-alcohols from C3H7OH to C5H11 OH. The difference between systems with TPB and sodium dodecyl sulfonate (AS) is also discussed. Some rules are worked out.

Key words: Middle phase microemulsions, TPB;Phase behaviour, Interfcial tension
