3. Micellar catalysis
Interfaces can be created by dissolving hydrophobic solutes in water or organic solvents, which can aggregate to form microheterogeneous solutions. These aggregate dispersions develop very broad interfaces with the dispersing solvent, creating the conditions in which interfacial catalysis can take place.
3.1 Hydrophobic solutes
To achieve such dispersions in water, hydrophobic solutes selected from the following four families must be used: surfactants, water-soluble polymers, planar heterocycles and condensed rings.
Surfactants are amphiphilic molecules with hydrophilic groups and hydrophobic chains (table 10 ).
Some proteins, enzymes and synthetic...
