摘要：通过化学活化有机磺酸前驱体，低温下制备了磺酸基功能化碳/硅材料（C/Si-SO 3 H），并将其用于大豆卵
磷脂与丙酸乙酯或丁酸甲酯催化合成短碳链结构磷脂的反应中，考察了反应温度、反应时间、催化剂用量及循
环次数对该酯交换反应的影响。采用 FTIR、Raman 及 Boehm 酸含量滴定等手段对 C/Si-SO 3 H 进行结构和表面
酸性质表征，以建立该催化剂的构效关系。结果表明，C/Si-SO 3 H 表面含有大量 Brӧnsted 酸性位点，因而催化
性能较为突出；当催化剂用量为反应原料总质量的 7%、40 ℃反应 6 h，短碳链结构磷脂中丙酸或丁酸的接入率
高达 18.33%或 16.23%，且 C/Si-SO 3 H 循环利用 4 次而无明显失活。

Abstract: A kind of sulfonic acid-functionalized C/Si (C/Si-SO 3H) material was synthesized at low
temperature via chemically activating organic sulfonic acid precursor and used for catalytic synthesis of
structured phospholipids rich in short-chain fatty acids by interesterification of soybean lecithin with ethyl
propionate or methyl butyrate. The influences of reaction temperature, reaction time, catalyst dosage and
catalyst recycling times on the interesterification were investigated. The structure and surface acid
properties of C/Si-SO 3H were studied by FTIR, Raman and Boehm titration method to establish its
structure-performance relationship. The results showed that C/Si-SO 3H surface contained a large number of
Brӧnsted acid sites, and its catalytic performance was outstanding. The incorporation ratio of propionic acid
or butyric acid was up to 18.33% or 16.23% under the conditions of C/Si-SO 3H dosage being 7% of raw
materials tatal mass, reaction temperature 40 ℃ and reaction time 6 h. Moreover, C/Si-SO 3H catalyst had
no obvious deactivation after being recycled for 4 times.
