【摘要】 <正> 1,4-双(邻氰基苯乙烯基)苯(BCSB)是一种用于聚酯和聚酰胺纤维的荧光增白剂,它与纤维的结合牢度强,洁白程度高。其合成一般经过邻氰基甲苯光氯化,邻氰基氯苄酯化,邻氰基苄基膦酸二乙酯与对苯二甲醛缩合等三步反应。所以BCSB产物更多还原

【Abstract】 The HPLC methods for analysis of fluorescent whitening agent 1,4-bis(o-cyanostyryl) benzene and its related products with a ZORBAX ODS column of particle size 5um have been established. Its purity can be determined with an eluent of rnethanol -water (82 : 18,V/V) and the related products with tetra-hydrofuran methanol-water (1 : 59 :40,V/V/V). The value of detection wavelength are UV 274 and 361 nm. respectively. The flow rate is 1 ml/min and the temperature 40℃. The methods are simple, rapid and efficient.更多还原
