摘　　要：综述了用2,2'-二甲基-5,5'-二丙氧基联苯胺和5,5’-二丙氧基联苯胺作为重氮组分的直接染料的合成和检测。TLC检测染料的纯度,其最大可见吸收为485-601nm,摩尔消光系数为2.2×104-6.4×104L/mol.cm,用ESMS确定染料的化学结构。这类直接染料无致癌诱变性,并具有良好的应用和牢度性能。有20篇参考文献。The synthesis and evaluations of direct dyes prepared from 5,5'-dipropoxybenzidine and 2,2'-dimethyl-5,5'-dipropoxybenzidine as the diazo components were reviewed with 20 references. The purities of the dyes were determined by TLC, their maximum absorptions were at 485-601 nm, molar extinction coefficients were 2.2 × 104- 6.4 × 104 L/mol.cm, their structures were confirmed by ESMS. These direct dyes were found to be non-carcinogenic and with good application properties and fastnesses.
