Abstract
Chinese raw tall oil samples, which were obtained from pulp and papermaking factories in Qingzhou and Jiamusi, were first divided into acidic and neutral parts with a diethylaminoethyl-Sephadex (DEAE-Sephadex) gel column. The acidic components were then analyzed qualitatively and quantitatively by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). The results obtained are as follows: Most of the compounds that comprised 0.1% or more of the components were identified. Secodehydroabietic, 8,15-pimaradienoic, 8,15-isopimaradienoic, 7,13,15-abietatrien-18-oic acid, and others were found for the first time in Chinese tall oil; they have not been found in Chinese fatty rosin. Docosan-1,22-dioic acid was also found in tall oil for the first time.
