                 摘要:通过溶胶-凝胶法和浸渍法制备了负载 Zn 的 SiO 2 包覆 Fe 3 O 4 (Zn-Fe 3 O 4 @SiO 2 ),采用 SEM、TEM、XPS、
                 Py-IR、VSM、EDS 对其进行了表征。将 Zn-Fe 3 O 4 @SiO 2 用于催化大豆卵磷脂(SLs)与短碳链脂肪酸(丙酸和
                 丁酸)间的酸解反应来制备新型短碳链结构磷脂(SCSPLs)乳化剂,并对 SCSPLs 进行了性能测定。结果表明,
                 核壳结构 Zn-Fe 3 O 4 @SiO 2 磁性微球负载了大量的活性组分 Zn,因而可高效催化制备 SCSPLs,在 m(SLs)∶m(C3∶
                 0)∶m(C4∶0)=1∶4∶4、催化剂用量为原料总质量的 5%、反应温度为 50  ℃、反应时间为 5 h 的条件下,SCSPLs
                 的短碳链脂肪酸接入率可高达 78.15%±1.08%(丙酸和丁酸的接入率分别为 35.43%±0.62%和 42.72%±0.55%),
                 且 Zn-Fe 3 O 4 @SiO 2 可通过外加磁场进行简单分离,循环 5 次而无明显失活;与 SLs 相比,SCSPLs 的乳化性、
                 分散性和氧化稳定性均得到很大的提高。

                 Abstract: Zinc-loaded iron oxide coated with silica (Zn-Fe 3O 4@SiO 2) was  prepared by sol-gel and
                 impregnation  methods, and  characterized  by SEM, TEM, XPS,  Py-IR, VSM and  EDS for analysis on
                 textural and magnetic properties. The Zn-Fe 3O 4@SiO 2 obtained was then used in catalyzing the acidolysis
                 of soybean lecithins (SLs) with short-chain fatty acids (propionic acid and butyric acid) for synthesis of
                 novel emulsifiers of short-chain structured phospholipids (SCSPLs), followed by investigation on the main
                 physicochemical properties of the SCSPLs synthesized. The results showed that the active component Zn,
                 loaded in the  core-shell Zn-Fe 3O 4@SiO 2  magnetic microspheres, effectively facilitated the  synthesis of
                 SCSPLs. When the m(SLs)∶m(C3∶0)∶m(C4∶0)=1∶4∶4, the catalyst dosage was 5% of total mass of
                 raw materials, the reaction temperature was 50  ℃, and the reaction time was 5 h, the maximum short-chain
                 fatty acid incorporation  of SCSPLs  reached 78.15%±1.08% with 35.43%±0.62%  of propionic acid and
                 42.72%±0.55% of butyric  acid. Meanwhile, Zn-Fe 3O 4@SiO 2 could  be easily separated  with an external
