Über Naturwachse XVII: Die Zusammensetzung von Walrat

Natural Waxes XVII: Composition of Sperm Oil Two samples of sperm oil were separated by preparative gas chromatography into five fractions corresponding to the major peaks. Exact composition of the component acid and alcohol could be determined by micro-interesterification of the above fractions. Cetyl ester of lauric acid is the main component (> 80%) in the group of isomeric C₂₈-esters; the major components of C₃₀-esters and C₃₂-esters are cetyl myristate (～ 80%) and cetyl palmitate (～ 75%) respectively. Stearyl palmitate (55%) dominates in the group of C₃₄-esters and stearyl stearate (～ 60%) is the major component in the group of C₃₆-esters. Experiments were also carried out to determine compositions of isomeric esters in the five gas chromatographic fractions from their mass spectra.
