通过将蔗糖亲油多酯(L-595)和亲水蔗糖单酯(L-1695)混合在水中，使自组织结构从六方转变为层状液晶。当角鲨烷、正十六烷、正十烷、正辛烷和正庚烷的质量比为1/1时，在水中虽然没有发现立方相，但生成了不连续的油胀立方相(I_1)或立方相微乳液。随着原油分子尺寸的减小，单一立方相区向含油量较高的方向移动，以间二甲苯和环己烷为油时，没有发现立方相。此外，从I1相的组成分析表明，在短链烷烃体系中，胶束的形状变得非球形。
The self-organized structure is changed from hexagonal to lamellar liquid crystals by mixing sucrose lipophilic multi-dodecanoate (L-595) with hydrophilic sucrose monododecanoate (L-1695) in water. Although no cubic phases are found in water, a discontinuous cubic phase (I1) with oil-swollen micelles or a cubic-phase microemulsion is produced upon addition of squalane, n-hexadecane, n-decane, n-octane and n-heptane at the weight ratio of L-1695/L-595=1/1. The small-angle X-ray scattering spectrum and the phase behavior show that the micelles are packed in a face-centered cubic array in the I1phase. The single cubic-phase region shifts to higher oil content with the decrease in the molecular size of oil and finally, no cubic phases are found with m-xylene and cyclohexane as oil. Furthermore, from the analysis of compositions of the I1phases, it is suggested that the shape of the micelles becomes non-spherical in the short-chain alkane systems.
