Abstrakt: The composition (wt %) of the fatty acids obtained by decomposition of castor oil fatty acid estolides and distillation was determined by a combination of spectroscopic (ultraviolet, nuclear magnetic resonance, infrared), chromatographic (thin layer on Silica Gel G modified with silver nitrate and ammonium hydroxide, gas liquid) and chemical (partial reduction and periodate/permanganate oxidation) techniques and found to be 16:0, 2.7; 18:0, 2.6; 18:1, 5.2; conjugatedcis,trans (trans,cis)-18:2, 34.4; conjugatedcis,cis-18:2, 9.7; conjugatedtrans,trans-18:2, 3.9; 9-cis,12-trans-18:2, 20.8; 9-trans,12-cis-18:2, 2.3; and 9-cis,-18:2, 18.4.
