Abstract
The solubization of the W/O microemulsion of NA(naphthenic acid)/kerosene/NH3· H2O system has been investigated.The effect of salt,cosurfactant (-alcohol) on solubization of the microemulsion has been studied by the theory of cohesive energies(theory of R-ratio).The results show that theory of R-ratio may explain the effect of concentration of salt,such as LiCl,NaCl,KCl,NaNO3,Na2SO4,NH4Cl,on maximum solubization (Φ m) of the microemulsion,but can not explain the differences of the effect of these salt on Φ m(to see Fig.1).We have found that,the rateQ(Q=z/r) of salt was correlated with the effect of salt on Φ m(to see Tab.1).Theory of R-ratio can only explain the effect of fraction mass of part alconols,such as n-octyl and n-heptyl and n-hexyl alcohol on Φ m,but can not explain the effect of isobutyl alcohol,n-butyl alcohol,n-pentanol and isoamyl alconol on Φ m (to see Fig.2).So theory of R-ratio has it's limitations in explaination of the phenomenons of solubization of W/O microemulsion.关键词
