Fluid and Chiral Ephedrinium Myristate Micellar Fibers

“…Sodium palmitate and myristate fibers of micrometer width in soap gels (“curds”) presumably constitute the oldest supramolecular assemblies known. , These fibers are stable in dilute aqueous solutions and have been isolated and spun in the dry state . Titrations with sodium hydroxide showed that they were only produced at pH ≥ 13 and that they rearranged to form planar crystals , at pH 9.…”

“…Sodium palmitate and myristate fibers of micrometer width in soap gels (“curds”) presumably constitute the oldest supramolecular assemblies known. , These fibers are stable in dilute aqueous solutions and have been isolated and spun in the dry state . Titrations with sodium hydroxide showed that they were only produced at pH ≥ 13 and that they rearranged to form planar crystals , at pH 9. Thiele proposed that an increase in Coulombic repulsion was responsible for the crystal to fiber conversion, although there should not be much difference in carboxyl group deprotonation at pH values of 9 and 13.…”
