摘要: The notion of "green chemistry " has encouraged even synthetic organic chemists to include water as a solvent. Incredible selectivities and activities can be achieved through the addition amphiphiles with defined structure. morphology supramolecular assemblies or associates formed by surfactants vary according temperature concentration. As rule, reactions are typically conducted using simple spherical aggregates, that is, micelles in nanometer range. strong polarity gradient present between hydrophilic surface hydrophobic core micelle means both nonpolar polar reagents solubilized. This solubilization results reactants becoming more concentrated within than surrounding phase leads an acceleration reaction causes selective effects. kinetic treatment micellar systems accomplished considering them microheterogeneous two-phase systems.
