Abstract
The specific heat capacities of {2-(hexyloxytriethoxy)ethanol (C6E4)+water} system have been measured from 280 to 333 K within the whole composition range by DSC. Changes of specific, apparent and partial molar heat capacities of investigated aqueous solution vs. composition and temperature, considered as an effect of structural transformations were analyzed in order to draw boundary between region where amphiphile molecules occur as monomers and small aggregates and the area in which the first micelles appear. For each solution, the temperature dependences of the differential heat flow were analyzed in order to find the curve of phase coexistence, i.e. the boundary between one- and two-phase areas for the examined system.
