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.
