The phase diagram of α-cyclodextrin/water/4-methylpyridine solutions, a system undergoing inverse melting, has been studied by differential scanning calorimetry, rheological methods, and x-ray diffraction. Two different fluid phases separated by a solid region have been observed in the high α-cyclodextrin concentration range (c⩾150 mg∕ml). Decreasing c, the temperature interval where the solid phase exists decreases and eventually disappears, and a first-order phase transition is observed between the two different fluid phases. © 2008 The American Physical Society URL:
