磺化大豆磷脂的结构和性能研究(Ⅰ)——磺化大豆磷脂的结构解析和理化性能

Study of structures and performances about the soybean lecithin sulfonate(Ⅰ)—structures and physical chemistry performances of soybean lecithin sulfonate

通过对磺化大豆磷脂SPS这种新型阴离子表面活性剂的化学和仪器分析 ,探明SPS中活性基团的种类、数量、部位及不同SO3 结合量对其表面张力、渗透力、乳化力等理化性能的影响 ,确定了SPS的结构与理化性能的关系。

Soybean lecithin sulfonate(SPS)is a new type anion surfactant.By using chemical and apparatus analysis,it is proved that the sorts,amounts and position of the active groups and combination amount of sulfur trioxid influence SPS’s surface tension,infiltration,strength and emulsification strength.So the relation of the structure and physical chemistry performances are established.
