摘　　要：合成了一种具有表面活性的阳离子型漂白活化剂N-[4-(十二烷基二甲基铵甲撑)苯酰基]己内酰胺溴化物(DBCB),采用核磁共振、质谱和红外光谱等方法对其分子结构进行表征,并探讨其表面活性以及对纺织品的漂白性能。结果表明,DBCB被成功合成,产率达72.8%,临界胶束浓度为6×10^(-3)mol/L,表面张力为37.66 mN/m,具有良好的乳化性能,低泡易漂洗。DBCB对棉织物、有色污渍纺织品和油渍灰尘纺织品具有良好的漂白性能,与过氧化氢反应生成的过氧酸对织物表面有色污渍的去除效果显著,洗涤后的白度值接近纺织品原有白度。A cationic bleaching activator N-[4-(dodecyl dimethylammonium methylene)benzoyl]caprolactam bromide(DBCB)with surface activity is synthesized.Its molecular structure is characterized using nuclear magnetic resonance,mass spectrometry and infrared spectroscopy.Its surface activity as well as bleaching performance on textiles are studied.The results show that DBCB is successfully synthesized with a yield of 72.8%.The critical micelle concentration of DBCB is 6×10^(-3)mol/L,the surface tension is 37.66 mN/m,and it has good emulsifying properties,low foaming and easy to rinse.DBCB exhibits excellent bleaching performance on cotton fabrics,textiles with colored stains and greasy dust.The peroxide acid generated by the reaction with hydrogen peroxide has a significant removal effect on colored stains of fabrics,and the whiteness value after washing can approach the original whiteness of textiles.
