Isolation of 11-cyclohexylundecanoic acid from butter

After fractionation using fractional distillation, recrystallization, urea treatment hydrogenation, and repeated urea treatment, a hitherto unknown acid has been isolated from butter fatty acid methyl esters. Gas–liquid chromatography followed by mass and infrared spectroscopy showed that the acid i...
