The reaction of dihydroxyanthraquinone (DHA) and amines in the presence of catalyst has been reported. We found that DHA reacted easily with hexamethylenediamine in chloroform or toluene without addition of any catalyst, and mono-or dihexamethylenediamine-substituted anthraquinone, a violet green co
Without addition of any metal ions or other catalysts, 1-chloroanthraquinone reacts readily with 6-aminocaproic acid or hexamethylenediamine in dimethylsulphone as solvent to give 1-(6-aminocaproic acid)anthraquinone and 1-(6-aminohexyl)amino]anthraquinone, respectively. 1,5-Dichloroor 1,8-dichloroa
A series of 1,5-diaryl-and 1,8-diaryl-substituted anthraquinone dyes, which contain wCOOH or groups, were prepared. The aryl-substituted wNH 2 anthraquinone dyes possess excellent thermostability and will keep their original colour in polycondensation with caprolactam at 260Γ280Β‘C. With di β erent ar
