Determination of Kinetic and Thermochemical Parameters of a Substitution Reaction at a Square-Planar Palladium(II) Complex in Water/AOT/n-Heptane Microemulsions by Flow Microcalorimetry

Calorimetric investigation of reaction Ca(NO3)2 + Na3PO4 in water and microemulsions saturated with CO2

“…In the study of the reaction, 2.7 mL microemulsion containing Na 3 PO 4 (0.05 mol L −1 in water pool) was filled in the sample cell and 50 μL microemulsion containing Ca(NO 3 ) 2 (0.125 mol L −1 in water pool) was added to the sample cell by a Hamilton syringe. Particular attention was paid to ensure the two reactant microemulsions of Na 3 PO 4 aqueous solution/AOT/hydrocarbon and Ca(NO 3 ) 2 aqueous solution/AOT/hydrocarbon having the same value of R and the same concentration of the droplet, which avoided the heat of mixing when the two microemulsions were mixed together 19–22. A portion of the product of nanoparticles was taken out from the sample cell after the reaction completed and was examined by transmission electron microscopy.…”

Mixed Surfactant Based Microemulsions as Vehicles for Enhanced Solubilization and Synthesis of Organoselenium Compounds

“…The physiochemical properties of such systems are often very different from those of unsolvated molecules or condensed phases being more or less influenced by confinement effects, inhomogeneous distribution, orientation order, and interfacial interactions. 9,10 In recent years, various research groups have shown an increased interest in the assimilation of additives in the microemulsion media. [11][12][13][14] The structure of the surfactant also plays a dramatic role in the properties of microemulsions and the amount of additive hosted by them.…”

“…Their structural characteristics offer the opportunity to solubilize and stabilize relatively large and otherwise insoluble molecules in the microemulsion core. The physiochemical properties of such systems are often very different from those of unsolvated molecules or condensed phases being more or less influenced by confinement effects, inhomogeneous distribution, orientation order, and interfacial interactions. , In recent years, various research groups have shown an increased interest in the assimilation of additives in the microemulsion media. − …”
