UNSATURATED SURFACTANTS

摘要

Provided herein are adducts derived via a Diels-Alder process, which adducts comprise a hydrophobic portion and a hydrophilic portion, wherein the hydrophobic portion is derived from a hydrophobic terpene, that comprises two conjugated double bonds or an isolated double conjugated bond with an allylic hydrogen atom, and which has from 10 to 30 carbon atoms, wherein said hydrophilic portion: a) is derived from a dienophile which comprises a double-bonded pair of carbon atoms and at least one adjacent activating group; and b) has at least one hydrophilic group, present in the dienophile prior to, or introduced during or after, the formation of the adduct. The adducts are useful in preparing various types of surfactants known to those skilled in the art as being preparable from conventional fatty acids.
