Abstract

Author studied on the isolation technique and properties of the products obtained by the reaction of soybean oil with maleic anhydride. Before studying above purpose, oleic acid and linoleic acid contained in soybean oil were reacted with maleic anhydride. Thin-layer chromatography using silica coated plate and solvent system consisting of petroleum ether-diethyl ether = 7:3∼5:5 (v/v) resulted in good effects on the isolation of maleic anhydride adducts. Four fractions were separated and fraction No. 2 were analyzed by IR & UV spectrophotometer, obtaining the following conclusions. In the case of oleic acid adduct and linoleic acid adduct, it were conjectured that the succinic acid type adduct was formed. In the case of conjugated $C_{18}$ fatty acid adduct, cyclohexene type adduct was formed which differed from oleic acid and linoleic acid adduct.

말레酸化大豆油의 附加生成物의 分別과 그 特性을 究明하기 위하여 大豆油 助成 成分인 올레酸과 리놀酸을 말레酸無水物과 反應시켜, 이를 TLC에 依하여 分別하였다. 展開溶劑로서는 石油에테르 : 디에틸에테르 = 7 : 3∼5 : 5(vol/vol)에서 가장 分別이 잘 되었으며, 4區分으로 各各 分別되었으며, 이中에서 主生成物인 第 2區分을 IR 및 UV에 依하여 儉素한 結果는 올레酸附加物과 리놀酸附加物은 succinic acid 型 附加를 하고 있으며, 짝지은 디엔 $C_{18}$ 脂肪酸은 cyclohexene型의 附加를 이루고 있음을 確認 하였다.
