摘要
从天然原料植物——茶粕(Camellia Oleifera Abel meal)、无患子(Sapindus Mukorossi Gaertn)和皂荚(Gleditsia Sinensis Lam)中提取非离子表面活性物质,并对其表面活性的影响因素和复配增效性进行研究。结果表明,上述天然原料经Sanherb最佳工艺提取纯化后,所得提取物表面活性均优于原料;在酸性、高温及二元复配条件下,可增强提取物及相关复配体系的表面活性,而盐度、水硬度对各提取物表面活性的影响不明显。当以Rosen理论推算出的比例对各提取物进行二元复配时,m(无患子提取物)∶m(皂荚提取物)=1.58∶1.00体系(体系Ⅲ),形成胶束能力比单一组分增强了76%,m(油茶粕提取物)∶m(皂荚提取物)=1.90∶1.00体系(体系Ⅱ)的表面张力比单一组分减少10.50%,二者均具有较为明显的协同增效作用;泡沫性能测试发现,复配后的二元体系与单一组分相比较,具有更优良的泡沫性能,其中m(无患子提取物)∶m(皂荚提取物)=1.58∶1.00体系(体系Ⅲ)表现最佳。
The method of extraction and purification of 3 nonionic surfactants from Camellia Oleifera Abel meal,Sapindus Mukorossi Gaertn and Gleditsia Sinensis Lam were researched respectively,in addition,the influencing factors of their surfactant activity and their complex synergism were evaluated as well. The experimental results show that,after extraction and purification,the surfactant activity of the final extracts were obviously superior to the original natural materials. The influence factors on surfactant activity also showed that their surfactivity were enhanced while in acidic conditions,high temperature and binary mixed systems,but the effects of salinity and the hardness of water on their surfactivity were not obvious. Results showed that while the extracts were compounded in the proportion which calculated and conclued based on Rosen theory,the ability of m（ Sapindus Mukorossi Gaertn extracts） ∶ m（ Gleditsia Sinensis Lam extracts） = 1. 58∶1. 00system（ systemⅢ） to form micelles increaed by 76% than the single component while the ability of m（ Camellia Oleifera Abel meal extracts） ∶ m（ Gleditsia Sinensis Lam extracts） = 1. 90 ∶ 1. 00 system（ system Ⅱ） to reduce the surface tension enhanced by 10. 5%,which indicated both of them have synergistic effect. Furthermore,the results of foam property testing indicated that,compared with the single component,the binary mixed systems showed excellent foam property,especially the m（ Sapindus Mukorossi Gaertn extracts） ∶ m（ GleditsiaSinensis Lam extracts） = 1. 58∶1. 00 system（ systemⅢ） performed best.
