Abstract
Summary: A fractionation of lanolin was effected by contacting lanolin with urea in the presence of methyl alcohol. About 6–8% of the lanolin formed a urea adduct which, upon decomposition, yielded a hard, nontacky wax fraction. In addition to the wax fraction, a fluid fraction and a sticky semi‐solid were also obtained. The latter two fractions were obtained by the solvent extraction of the nonadduct‐forming material from the urea adducts.The fluid fraction, obtained in 71% yield, is a viscous liquid at room temperature. The fluid properties of the fraction can be improved by acetylation.Keywords
