“…The effect of headgroup size on rate constants for ether formation is opposite to that with EO surfactants, where reaction was faster with surfactants having a shorter headgroup [12,14]. Reaction in C 12 G 3 is faster than in C 9 G 1 and C 12 G 2 .…”

“…Although all solutes enter the palisade layer, concentrations of very hydrophilic ions are generally less in the palisade layer of a nonionic surfactant colloid than in the bulk solvent [12,19]. The observed differences in rate constants supports formation of ethers on all of the sugars in the headgroups; breakdown of ethers close to the water interface (C 9 G 1 ) should be faster than those closer to the hydrophobic region because they are in effectively much higher OH − concentrations.…”

“…Bunton, Savelli and others have shown this to be the case for reactions in micellar media. [26,[35][36][37][38] For instance, the type of reaction medium -homogeneous solution or micellar solution based on cationic surfactant -has been found to be decisive of the reaction of sulfonate esters in the presence of equimolar amounts of bromide and hydroxy ions. Without surfactant present attack by hydroxy ions dominates.…”
