Microemulsions are compounded separately with H_2O and different concentrations of sucrose solutions as aqueous phase at mass ratio 1∶1∶2 of CTAB/1-butanol/benzene and 30 ℃.The conductivity of microemulsion with different content of aqueous phase was measured.Microemulsion region and conductivity of microemulsion with 0-0.15 mol·dm~(-3) sucrose solution are similar to microemulsion with water.Microemulsion region of microemulsion with 0.15-0.85 mol·dm~(-3) sucrose solution is similar to microemulsion with water,and the conductivity is more smaller.Microemulsion region and conductivity of microemulsion with 0.85-2 mol·dm~(-3) sucrose solution are more smaller than microemulsion with water.
