【摘要】：以制備的Brφnsted-Lewis酸性離子液體[HO_3S-(CH_2)_3-mim]C1-xFeCl_3為催化劑,大豆油為原料,通過酯交換反應(yīng)制備生物柴油�？疾齑加臀镔|(zhì)的量比、催化劑的用量、反應(yīng)溫度和反應(yīng)時間等因素對酯交換反應(yīng)的影響。在此基礎(chǔ)上運用響應(yīng)面分析法得出合成生物柴油的最佳工藝條件為n(醇):n(油)=16:1,催化劑用量為原料大豆油質(zhì)量的8%,反應(yīng)溫度為120℃,此條件下反應(yīng)24 h生物柴油的產(chǎn)率可達94.1%,與回歸模型預(yù)測的實驗結(jié)果相當(dāng)。Brφnsted-Lewis酸性離子液體催化劑與產(chǎn)品易于分離,在重復(fù)使用6次以后,仍保持良好的催化活性。
[Abstract]:Preparation of Br 蠁 nsted-Lewis acidic Ionic liquids. [HO_3S-(CH_2)_3-mim] C1-xFeCl3 was used as catalyst and soybean oil as raw material to prepare biodiesel by transesterification. The amount of catalyst. The effects of reaction temperature and reaction time on the transesterification were studied. Based on the analysis of the reaction surface, the optimum reaction conditions for the synthesis of biodiesel were obtained as follows: n (n: n). The amount of catalyst is 8% of the quality of raw soybean oil, and the reaction temperature is 120 鈩，
