Composition of acidic components in Chinese raw tall oil

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.
