Temperature dependent phase behavior of pseudo-ternary Gemini surfactant + 1-hexanol (1 : 5 molar ratios)/oil/water systems is reported from 0°C to 65°C. The influence of nature of hydrocarbon oil and type of electrolytes (weak as well as strong) has been investigated on the temperature induced phase behavior of the ternary system. At surfactant concentration,Φs=40%, a “nose-shaped” microemulsion region is observed. Below one-phase microemulsion region,Lαphase appears. The presence of NaCl decreases the domain size of1Φmicellar region whereas oxalic acid first decreases the domain belowΦw<18and then increases aboveΦw>18in the lower boundary of the phase diagram. The critical weight fraction of waterΦwcridecreases in presence of both electrolytes. However,Φwmaxincreases in presence of oxalic acid and remains constant in presence of NaCl as compared to salt-free system. Furthermore, when cyclohexane was replaced by a longer straight chain hydrocarbon, dodecane, the domain of the one-phase microemulsion region is tremendously increased.
