The effects of short-chain alcohols on the phase behavior, solubilities and solubilization ability in the microemulsion systems cetyltrimethyl ammonium bromide (CTAB) or cetylpyridinium bromide (CPB) or 1-hexadecyl-3-methylimidazolium bromide (C16mimBr)/1-propanol or 1-butanol or 1-pentanol/n-octane/brine were investigated with the d-g fishlike phase diagram. The phase diagram was affected greatly by alcohols, and the magnitude of the middle phase region in the fish body is in the order 1-propanol greated than greated than 1-butanol greated than1-pentanol. With the carbon chain length becoming shorter, more alcohol molecules are needed to balance the interfacial layer. Nearly all surfactants enter into the interfacial layer and little remains in aqueous or oleic phase. However, alcohols dissolve in the aqueous and oleic phases, besides they enter into the interfacial layer. The solubilization ability of the microemulsion system is mainly affected by the alcohols and the order is 1-pentanol greated than 1-butanol greated than 1-propanol.

The phase behavior and solubilization of the quaternary system AEO-9/AS/n- butanol /alkane/NaCl solution were investigated with delta-gamma and epsilon-beta fishlike phase diagrams. Two kinds of diagrams were plotted and compared in their shapes, HLB plane equations and solubilization power representations. Their HLB plane equations were used to calculate the composition of the hydrophile-lipophile balanced interfacial layer. It is found that the synergism between AEO-9 and AS in the inter facial layer in solubilization power exists. The influences of oil and aqueous medium on the epsilon-beta fishlike phase diagram were also discussed.
