Anwendungen
OccurrenceArachidic acid is a saturated long-chain fatty acid and a minor constituent of peanut oil, coconut oil and corn oil.
VerwendenArachidic acid is used in the manufacture of pharmaceuticals, soaps, cosmetics, and food packaging because of its surfactant-like properties. Arachidic acid was also used for the dispersion of the monolayer. By addition of an appropriate amount of arachidic acid to a solution of [Eu(tta)3(phen)] in chloroform, stable monolayers consisting of [Eu(tta)3(phen)] and arachidic acid were obtained, and the [Eu(tta)3(phen)] were found to be dispersed homogeneously in the monolayer.
