    摘要:

    制備Zr改性的固體超強(qiáng)酸S2O2-8—TiO2/Fe3O4作為脂肪酸甲酯的合成催化劑，通過單因素和正交試驗(yàn)考察了該催化劑催化合成脂肪酸甲酯的催化特性。試驗(yàn)表明：甲醇脂肪酸液料比3mL/g，催化劑投入量12%，反應(yīng)溫度65℃，反應(yīng)時(shí)間6h的條件下，酯化率達(dá)到94%，產(chǎn)品得率90%，且催化劑回收再次利用效果較好。

    Abstract:

    Solid acid catalyst can be applied to the transterification as a substitute of homogeneous acid catalyst. Zr-modified solid super acid S2O2-8—TiO2/Fe3O4 was prepared as the catalyst for FAME production and the catalysis activity was studied by single-factor and orthogonal experiments. The results show that the esterification rate and product yield can realize to 94% and 90% respectively when the volume to mass ratio of methyl alcohol to acid is 3mL/g, the reaction temperature is 65℃, the reaction time is 6h, and the amount of catalyst is 12％ of mass of fatty acid. The recovered catalyst can be reused effectively.  
