α-磺酸基-月桂酰氧乙基-二甲基十二烷基溴化铵的合成与性能评价

Synthesis and performance evaluation of α-sulfonic acid-lauryl acyl oxygen ethyl-dimethyl lauryl ammonium bromide

以月桂酸、氯磺酸、N,N-二甲基乙醇胺、溴代十二烷为原料,通过磺化反应、季铵化反应及酯化反应合成了一种新型的两性双子表面活性剂,即α-磺酸基-月桂酰氧乙基-二甲基十二烷基溴化铵双子表面活性剂。用红外光谱对最终合成物的结构做了初步的表征,评价了合成物的表面活性、复配性能、乳化性能、起泡性能。

In this paper,using raw materials of lauric acid,chlorosulfonic acid,N,N-DMEA and bromdecane,synthesized a new type of amphiprotic gemini surfactants,i.e.α-sulfonic acid-lauryl acyl oxygen ethyl-dimethyl dodecyl ammonium bromide.And characterized the structure of the final outcome by the infrared spectrum,and evaluated the surface activity,compound property,emulsification and foamability of the synthetic.
