中文摘要:
      为制备一种绿色乳化剂产品,采用湿法工艺以十二烯基琥珀酸酐(DDSA)和β-环糊精(β-CD)为原料成功制备十二烯基琥珀酸环糊精酯(DDS-β-CD)。通过傅里叶变换红外光谱(FT-IR)对DDS-β-CD结构进行了表征;热重分析(TGA)发现DDS-β-CD的热稳定性与β-CD相比有所降低,但是起始分解温度仍高达225 ℃,满足其在食品、日化、微胶囊等领域的应用;当DDS-β-CD的取代度大于0.198时,所测样品质量分数为6%的水溶液透光率仍可达97%以上。取代度为0.295的DDS-β-CD的亲水亲油平衡值(HLB)为16.520,说明其具有一定的起泡能力和乳化能力:泡沫稳定性较好为79.08%;对植物油和液体石蜡的乳化性能分别为991 s和545 s;DDS-β-CD质量分数为0.5%时的水包植物油乳液的起始平均粒径为4.42 μm,并具有良好的稳定性。
英文摘要:
      In order to prepared a green emulsifier product. Dodecenyl succinic acid cyclodextrin ester (DDS-β-CD) was successfully prepared from dodecenly succinic anhydride (DDSA) and β-cyclodextrin (β-CD) by wet process. The structure of DDS-β-CD was confirmed by fourier transform infrared spectroscopy (FT-IR). Thermogravimetric analysis (TGA) showed that the thermal stability of DDS-β-CD was lower than that of β-CD. However, the initial decomposition temperature was still as high as 225 ℃, which can meet its application in food, daily chemical and microcapsules. When the degree of substitution of DDS-β-CD was greater than 0.198, the transmittance of the sample with 6% mass fraction aqueous solution could still reach more than 97%. The hydrophile lipophilic balance (HLB) of DDS-β-CD with substitution degree of 0.295 was 16.520, indicating that it had foaming ability and emulsifying ability. The foam stability was better than 79.08%. The emulsifying properties for vegetable oil and liquid paraffin were 991 s and 545 s, respectively. When the DDS-β-CD mass fraction was 0.5%, the initial average particle size of the vegetable oil-in-water emulsion was 4.42 μm, and the emulsion had good stability.
