Stability of Diesel Microemulsion

Abstract Mix nonionic surfactants of Span80 and Tween80 series were used to prepare water��in��oil diesel microemulsion. Moreover�� the effects of alcohol��different proportion of Span80 and Tween80��and different proportion of alcohol and surfactant on the stability of diesel microemulsion were discussed. A series of pseudoternary phase diagram of Span80��Tween80/ diesel/n-amyl alcohol/water system were drawn.The final results show that the optimal conditions are obtained. The best mass ratio of Span80 to Tween80 is 4��6��the best auxiliary is ��n-amyl alcohol and the best mass ratio of auxiliary to surfactant is 0.4��1. The results were analysed based on HLB and interfacial bark theory.
