Studies on the N-Lauroyl-N-methylglucamide Based Microemulsion with epsilon-beta Fishlike Phase Diagram

Chai J., Yang X., Gao Y., Zhao J., Xu J.

Polish Journal of Chemistry

Vol. 81, nr 8

1505-1509

The microemulsion phase behavior of the quaternary system of N-lauroyl-N-methylglucamide (MEGA-12)/alcohol/n-octane/waterwas studied with aepsilon-beta fishlike phase diagram. The composition of the balanced interfacial layer was calculated by the - hydrophile-lipophile balanced (HLB) plane equation. The physicochemical parameters of the system were also obtained. The solubilization power was discussed.

Phase Behavior and Solubilization of NAPL/Water/n-Dodecyl polyglucoside/n-Butanol Microemulsion System

The phase behavior of the middle-phase microemulsion nonaqueous phase liquids (NAPLs)/water/n-dodecyl polyglucoside/n-butanol has been studied with Winsor type and - fishlike phase diagrams. The phase types, the phase volumes and the region of the middle-phase microemulsion were observed from Winsor phase diagram. From - fishlike phase diagram, the composition of the hydrophile-lipophile balanced interfacial layer was calculated. The solubilization power of the microemulsion for differentNAPLs was discussed, and the order of the solubilization power for three kinds of NAPLs is determined to be carbon tetrachloride > toluene > n-hexane.
