摘　　要：以4,4′-二氨基二苯乙烯-2,2′-二磺酸、2,4,6-三氯-1,3,5-三嗪、二辛基甲基叔胺、4-氨基苯甲酸为原料,经过连续缩合反应制备出一种结构新颖的DSD酸-三嗪-四辛基双季铵盐荧光增白剂。采用傅里叶变换红外光谱(FT-IR)和核磁共振氢谱(1 H NMR)对目标化合物进行结构表征,并对荧光性能、增白效果、色度指数、表面活性和表面整理作用进行了测试。结果表明:DSD酸-三嗪-四辛基双季铵盐荧光增白剂具有较强的荧光发射性能;对滤纸进行染色增白处理后,白度值由84.58增加至124.81,且滤纸外观更加光滑平整;目标化合物具有表面活性作用,使水溶液的临界胶束浓度为7.68×10^(-3 )mol/L,表面张力为30.81 mN/m。With 4,4′-diaminostilbene-2,2′-disulfonic acid,2,4,6-trichloro-1,3,5-triazine,dioctylmethyl tertia⁃ry amine and 4-aminobenzoic acid as raw materials,a novel DSD acid-triazine-tetra-octyl bis-quaternary am⁃monium salt fluorescent whitening agent is prepared through consecutive condensation reaction.The structure of the purified target compound is characterized by FT-IR and 1 H NMR,and the fluorescence property,whiten⁃ing effect,chromaticity index,surface activity and surface finishing are tested.The results show that the DSD acid-triazine-tetra-octyl bis-quaternary ammonium salt fluorescent whitening agent has strong fluorescence emission performance.After the filter paper is dyed and whitened with the target compound,the whiteness in⁃creases from 84.58 to 124.81.The appearance of the treated filter paper sample is smooth.The target com⁃pound has surface activity.The critical micelle concentration of the target aqueous solution is 7.68×10^(-3) mol/L,and the surface tension is 30.81 mN/m.
