摘　　要：为了深入探索Bola型表面活性剂的特性,提出Bola型表面活性剂的合成及胶束化行为研究。将L-酪氨酸与1,12-二氨基十二烷作为Bola型表面活性剂的合成原料,得到性状为淡黄色粉末的Bola型表面活性剂产物;分别利用电导率法和等温滴定量热法确定Bola型表面活性剂的临界胶束浓度,并对不同浓度Bola型表面活性剂的胶束化热力学行为进行统计,确定熵的增加(即系统无序性的增加)是Bola型表面活性剂胶束化过程的主要驱动力。In order to explore the characteristics of Bola surfactants,the synthesis and micellization behavior of Bola surfactants were proposed.L-tyrosine and 1,12-diaminododecane were used as raw materials for the synthesis of Bola surfactant,and the Bola surfactant product with light yellow powder was obtained.The critical micelle concentration of Bola surfactants was determined by conductivity method and isothermal titration calorimetry method respectively,and the thermodynamic behaviors of micellization of Bola surfactants with different concentrations were statistically analyzed.It was determined that the increase of entropy(that is,the disorder of the system) was the main driving force of the micellization process of Bola surfactants.
