Abstract
Water–sodium dodecylsulfate–triethanolamine–1-pentanol–1,1,2,2-tetrafluorodibromoethane microemulsions of five compositions with different water–hydrocarbon ratios at a constant total surfactant+co-surfactant concentration of ~ 22 wt.% are obtained and their specific isobaric heat capacity and specific conductivity are measured. The temperature and concentration dependences of the mentioned properties of microemulsions are analyzed and interpreted from the standpoint of structural changes in the five-component system.
