The quasi-three-component phase diagrams of microemulsion system composed of AS/CTAB/alcohol/n-C₇H₁₆/H₂O and SDS/CTAB/alcohol/n-C₇H₁₆/H₂O have been used to investigate the formation of middle phase microemulsion as function of the kinds of salt and alcohols.It is found that alcohol plays a significant role in formation of microemulsion (ME) and middle phase microemulsion (MPME);and the alcohol mixture such as n-C₃H₇OH+n-C₄H₉OH and i-C₃H₇OH+n-C₄H₉OH are superior in microemulsion formation to the single ones;as to the effect of salts,the protosalt appears more favourable.
