【摘要】 对合成得到的季铵盐型十六烷基阳离子咪唑啉进行了多项表面活性测定 ,其中表面张力为 48.2～ 5 2 .3kN·m-1;HLB值评价为 8,属水包油型表面活性剂 ;在硬水中的稳定性评价良好 ;发泡力大致与平平加O(n =15 )相当。证实它具有良好的性能。更多还原

【Abstract】 Some items on surface activity of positive ion imidazoline surfactants were determined.As a result,the surface tension was 48.2-52.3 kN·m -1 and was mutable when concentration of the surfactants changed;HLB measure was 8,to be regarded as O/W surfactants;the stability in hard water was good;the foaming power of the surfactant in water was nearly the same as that of peregal O-15.更多还原
