Microemulsions

Ionic Liquids in Microemulsions—A Concept To Extend the Conventional Thermal Stability Range of Microemulsions

“…Qualitative effects on several variables on changes in phase behavior were summarized by Bellocq et al for anionic surfactants. 87 These effects are summarized in Table II-1. Ethoxylated alcohols are the most widely used non-ionic surfactants, they are prepared by the reaction of ethylene oxide with aliphatic or aromatic alcohols. 88 A common abbreviation for these surfactants is C i E j where i denotes the carbon number in the hydrophobic tail and j the repetition unit of oxyethylene groups: …”

Phase behavior of pseudoternary brine/alkane/alcohol-secondary alkanesulfonates systems

“…Since the identification of microemulsions by Schulman and coworkers in the early 1940's [1], their applications have been extended to numerous technological areas from tertiary (or enhanced) oil recovery (EOR) to nanoparticle synthesis [2][3][4][5].…”

“…Consequently, the phase behavior of these systems (water, oil, surfactant and cosurfactant) is very important and has been the subject of intensive studies [2,6,[10][11][12].…”

Giant optical non-linearities of critical micro-emulsions

“…Micro-emulsions are thermodynamically stable mixtures of an oil, water and a surfactant and often a cosurfactant (alcohol) [4]. Such Article published online by EDP Sciences and available at http://dx.doi.org/10.1051/jphyslet:01985004605018100 by a shell of surfactant molecules (inverted micelles) [4,5]. The stability of the system is partly controlled by attractive interactions between the micelles.…”
