Pressure And Temperature Induced Phase Transitions In Aqueous Surfactants

Various infrared spectroscopic parameters were used to study the pressure and temperature induced phase transitions in aqueous sodium alkenoates. It is demonstrated that thermodynamic parameters such as the critical micellization temperature or the critical coagelization pressure, as well as the structural changes that occur at these phase transitions, can be readily obtained with the state-of-the-art FT-IR technique.
