摘要：以油酸缩水甘油酯和甘油为原料，在固体酸催化剂（活性炭负载硫酸）作用下，通过开环反应制得了油

酸二聚甘油酯，并对合成条件进行优化。通过 FTIR 和 HNMR 对产物结构进行了表征，并将其用作柔软保湿剂
涂覆到面巾纸上，考察其对面巾纸柔软度、保水率、抗张指数及亲水性的影响。得到的最佳合成条件为：n(油
酸缩水甘油酯)∶n(甘油)=1∶5，催化剂用量为反应物总质量的 6‰，反应温度 70 ℃、反应时间 4 h。结果表明，
油酸二聚甘油酯具有优异的柔软保湿性能，在油酸二聚甘油酯添加量为甘油水溶液质量的 0.25%时，面巾纸的
柔软度〔（49±2）mN〕优于市面上有机硅柔软剂（氨基硅油）改性的面巾纸柔软度〔（68±2）mN〕，这是由于大
分子柔软剂能够对纤维表面的缺陷进行修复，从而使纤维表面平整度提升。且在温度为 30 ℃、湿度为 60%时，
油酸二聚甘油酯型柔软保湿剂涂覆后的面巾纸的保水率（98.2%±0.2%）也略高于有机硅柔软剂涂覆后的面巾纸
的保水率（96.5%±0.2%）。

Abstract: Dipolyglycerol oleate was prepared by ring-opening reaction of glycidyl oleate with glycerol in
the presence of solid acid catalyst-sulfuric acid supported on activated carbon, optimize the synthesis

conditions, and characterized by FTIR and HNMR. Then, as a softener and moisturizer, its effects on the
softness, water-retention rate, tensile index and hydrophilcity of facial tissue paper were studied. The
optimal synthesis conditions were obtained as follows: n (glycidyl oleate)∶n (glycerol) = 1∶5, the catalyst
dosage was 6‰ of the total mass of the reactants, the reaction temperature was 70 ℃, and the reaction time
was 4 h.The results indicated that facial tissue paper, coated with dipolyglycerol oleate in glycerin aqueous
emulsion by a mass ratio of 0.25%, demonstrated better softness than that coated with silicone
softening(amino silicone oil) agent on the market with a value of (49±2) mN versus (68±2) mN. This could
be attributed to the fiber surface flatness improvement because of the surface defect repairment by
macromolecular softener. Moreover, it was found that the water-retention rate (98.2%±0.2%) of facial
tissue paper coated with dipolyglycerol oleate was slightly higher than that of ones coated with silicone
softening agent (96.5%±0.2%) at 30 ℃ and a humidity of 60%. All these data proved that dipolyglycerol
oleate had excellent softening and moisturizing capacities.
