Owing to the large difference in cohesive energy and volatility between the two component substances, the phase behavior is rather complex particularly in the CTAB-rich region. It was found that CTAB and OIPh produce 1: 3 intermolecular complex in addition to the 1: 1 complex already reported. Both of the complexes undergo incongruent melting at about 305 K and 365 K, respectively. Formation of another 2: 1 complex in the high temperature region is proposed. The 2: 1 complex produces solid solution of mesomorphic nature in a limited composition range with the high-temperature metastable phase of CTAB. Thermodynamics of formation of the 1: 1 complex in the crystalline state is discussed., application/pdf}, pages = {5--13}, title = {Phase behavior of CTAB:o-iodophenol system in the temperature range 280-430 K}, year = {1999}, yomi = {エンドウ and スガ} }
