The phase behavior of microemulsions of brine, hydrocarbon, alcohol, and a pure alkylarylsulfonate-sodium 4-(1'-heptylnonyl)benzenesulfonate (SHBS or Texas No. 1)-was investigated under conditions where four equilibrium liquid phases are present. Systematic progressions from three phases to four phases (two microemulsion phases) to three phases with changing temperature and salinity are reported for the first time. The observed sequences of phase splits are described in terms of inferred phase diagrams. The collapse of a four-phase tie tetrahedron into a critical tie triangle is discussed.
