<p>This invention is for di-substituted surfactant precursors, surfactants prepared from them, methods of making the di-substituted surfactant precursors and derived surfactants, and to surfactants having the properties of the described surfactants. The di-substituted surfactant precursors and surfactants are derived from admixing water, surfactant, a hydrolysis catalyst, and an initial quantity of a substituted three-membered heterocycle (a substituted l-oxacyclopropane, a substituted 1-thiacyclopropane, or a substituted l-azacyclopropane) and sustaining an emulsion admixture of the di-substituted surfactant precursor, the water, the heterocycle, the surfactant, and the catalyst to yield the di-substituted surfactant precursor. The di-substituted surfactant precursor is further functionalized to achieve desired hydrophilic properties. A new surfactant product is ultimately provided affording a new combination of (in aqueous admixture) critical micelle concentration, viscosity, and clarity properties.</p> |
