Abstract
A perdeuterated potassium palmitate/deuterium oxide mixture (66/34% by weight respectively) weas examined using time resolved x-ray diffraction. The dynamic phase initial diagram indicated that upon heating, the crystalline bilayer phase undergoes a transition to a liquid-crystalline phase at approximately 75[ddot]C via two metastable states. One of the metastable states is a disordered cyrstalline bilayer and the other is a liquid crystalline bilayer. Upon subsequent cooling, the liquid-crystalline bilayer transforms directly to a getl bilayer phase.Keywords
