          摘要:

          以四氯化鋯、磷鉬酸水合物、1,2,4,5-苯四甲酸和(3-巰基丙基)三甲氧基硅烷為原料,通過原位合成法及接枝共聚法制得負載磷鉬酸的磺酸基功能化UiO-66(HPMo@UiO-66-SO3H)。采用XRD、FTIR、SEM、EDS、XPS、N2吸附-脫附和TG-DTG對其進行了結構表征;應用HPMo@UiO-66-SO3H促進大豆卵磷脂與中碳鏈脂肪酸(辛酸和癸酸)酯交換合成富含辛酸和癸酸的中碳鏈結構磷脂,通過正交實驗優化了反應條件,并對比了HPMo@UiO-66-SO3H與HPMo、UiO-66、HPMo@UiO-66和UiO-66-SO3H的反應活性,考察了HPMo@UiO-66-SO3H的循環利用性。結果表明,HPMo@UiO-66-SO3H具有介孔結構,并含有大量HPMo和磺酸基活性組分,且組分間可顯著協同促進中碳鏈結構磷脂的合成反應;當HPMo@UiO-66-SO3H含量為大豆卵磷脂、辛酸和癸酸總質量的百分之5,m(大豆卵磷脂)∶m(辛酸)∶m(癸酸)=1∶10∶10,50 ℃下反應4 h時,產物的中碳鏈脂肪酸接入率高達百分之94.31(辛酸和癸酸接入率分別為百分之44.21和百分之50.10);HPMo@UiO-66-SO3H可循環利用5次活性無明顯下降。提出了HPMo@UiO-66-SO3H促進酯交換制備中碳鏈結構磷脂過程的可能反應機理。

          Abstract:

          Sulfonic acid functionalized phosphomolybdic acid incorporated-UiO-66 (HPMo@UiO-66-SO3H) was prepared by an in-situ graft copolymerization method using zirconium (Ⅳ) chloride, phosphomolybdic acid hydrate, 1,2,4,5-benzenetetracarboxylic acid and (3-mercaptopropyl) trimethoxysilane as raw materials, and characterized by XRD, FTIR, SEM, EDS, XPS, N2 adsorption-desorption and TG-DTG. HPMo@UiO-66-SO3H was used to prepare medium-chain structured phospholipids enriched in caprylic acids and capric acids through transesterification between soybean lecithins and medium-chain fatty acids (caprylic acids and capric acids), and the reaction conditions were optimized by orthogonal experiment method. Moreover, the reactivity of HPMo@UiO-66-SO3H was compared with HPMo, UiO-66, HPMo@UiO-66 and UiO-66-SO3H materials, and the recycling of HPMo@UiO-66-SO3H was researched as well. As a result, it was certified that HPMo@UiO-66-SO3H exhibited a mesoporous structure possessing numerous HPMo and sulfonic acid active components, and a promising reactivity for the synthesis of medium-chain structured phospholipids due to the synergistic effect of the two components. The incorporation of medium-chain fatty acids in product reached as high as 94.31percent with 44.21 percent of caprylic acid and 50.10 percent of capric acid at 50 ℃ within 4 h when the HPMo@UiO-66-SO3H dosage was 5 percent of the total mass of soybean lecithins, caprylic acids and capric acids, and the m(soybean lecithins)∶m(caprylic acids)∶m(capric acids) was 1∶10∶10. Noticeably, HPMo@UiO-66-SO3H could be recycled 5 times with no obvious deactivation. A probable reaction mechanism of medium-chain structured phospholipid synthesis using HPMo@UiO-66-SO3H responsible for the process is presented.
