Synthesis of Cationic Bolaform Surfactant and Its Application Performance of as levelling agent
Abstract Dodecane-l,12-bis(oxy-2-hydroxy-propyl trimethyl ammonium chloride) (DBA2-12), which belongs to the cationic bolaform surfactants, was synthesized by two-step reactions in this study.The structure of the product was characterized by IR.The IR spectra showed the characteristic bands corresponding to the stretching vibration of C-N, C-O, and-OH groups.The influence of DBA2-12 on the kinetics and thermodynamics of the dyeing of acrylic fibers with cationic yellow X-5GL were investigated.The results showed that the bolaform surfactant had significant retarding effect for cationic dye, the dyeing rate constant and equilibrium dye-uptake was decreased, half-dyeing time was increased by the addition of surfactant DBA2-12.Meanwhile, surfactant DBA2-12 declined the partition coefficient, affinity and dye saturation value.It is concluded that bolaform surfactant DBA2-12 can be used to control dyeing rate of cationic dyes on acrylic fibers.
