摘要：

The state of water in the Aerosol OT (AOT) / isooctane reversed micelle solutions was studied by a microcalorimeter of conduction type. The molar enthalpy changes of water were obtained by mixing AOT solutions of various R values with those at R of zero, where R means the molar ratio of water to surfactant, AOT. The observed enthalpy values at larger were endothermic, whereas those at smaller R were exothermic. An enthalpy curve against R was drawn by adding consecutively the enthalpy changes, showing a maximum at R of 2. This feature was qualitatively discussed in terms of the state of water in reversed micelles. © 1990.
