The synthesis of azelaic acid through oxidation of oleic acid with the aqueous potassium permanganate(KMnO 4) has been studied by using the phase transfer catalyst (PTC). 采用高錳酸鉀作為氧化劑、分別使用四丁基溴化銨、 四乙基溴化銨和芐基三乙基氯化銨作為相轉(zhuǎn)移催化劑，考察了從油酸氧化制備壬二酸的行為。
The Fe_(3)O_(4) nanoparticle sol is prepared by liquid-phase coprecipitation and its surface is modified by oleic acid, then the Fe_(3)O_(4) nanoparticle coated with oleic acid is got. 通過液相共沉淀法制備了納米四氧化三鐵溶膠，利用油酸對納米粒子體進(jìn)行表面改性和萃取實(shí)驗(yàn)，獲得油酸包覆的四氧化三鐵微粒。
