PHYSICAL CHARACTERISTICS OF SYNTHESIZED 1-AMINO-4-(ARYLAMINO)ANTHRAQUINONE 2-ETHER DYES FOR SYNTHETIC-POLYMER FIBERS.

The synthesis and characteristics of a series of 2-ethers of 1-amino-4-(arylamino)anthraquinone by various preparative routes are described. Replacement of a bromine atom in the beta -position by a phenoxy group increased the molecular size.

Arylamination of Aminohalogenoanthraquinones

1-Amino-4-arylaminoanthraquinones (II) have been prepared in high yields by reacting 1-amino-4-chloroanthraquinone (Ia, 1 mol) with arylamines (6 mol) and anhyd.AlCl3 (5 mol) in nitrobenzene at room temperature. 1-Amino-2-bromoanthraquinone, 2-amino-1-chloroanthraquinone, 1-benzamido-4-chloroanthraquinone and 1-amino-5-chloroanthraquinone fail to give arylaminated products. 1-Amino-2,4-dibromoanthraquinone (Ic) gives only 4-arylaminated compounds (IIq-s) whereas 1-amino-8-chloroanthraquinone (Ie) gives 2-arylaminated derivatives (III).A plausible mechanism for the reaction has been suggested.The arylaminated compounds have been applied on polyester as disperse dyes and their dyeing properties evaluated.
