Thiel, W.,Mayer, R.,Jauer, E.-A.,Modrow, H.,Dost, H.
, p. 497 - 514 (2007/10/02)
53 Donor-acceptor substituted azo dyes of the benzene series were prepared by diazonium-coupling reactions (1a-s) or halogen-cyanide exchange (->2a-x, 3a-j).Described are the preparation of the amines 4a-m and the coupling compounds 5a-t and the procedure of diazotizing and coupling.The colouristic and spectroscopic data show that compounds of the general formula 1 are excellent brilliant blue azo dyes usefull for dyeing polyester material.
Process for the production of 2,4-dinitroanilines
-
, (2008/06/13)
A method for the preparation of 2,4-dinitroaniline from 1-chloro-2,4-dinitrobenzene comprising adding ammonia to melted 1-chloro-2,4-dinitrobenzene in such dosages that the temperature of the mixture does not exceed 120° C. and that the pressure does not exceed 3 bar. 6-halo-2,4-dinitroaniline may be produced from the so formed 2,4-dinitroaniline by neutralizing the suspension containing the 2,4-dinitroaniline with acid to give a pH of from the 6-halo-2,4-dinitroaniline. The 6-halo 2,4-dinitroaniline is useful in the preparation of dyestuffs.

-
, (2008/06/13)
Disperse dyes from cyano, chloro, or bromodinitroaniline and (2'-methoxy-5'-alkanoylaminoanilino)alkoxy or aryloxy alkanes impart blue shades with excellent colorfastness properties and shade reproducibility on polyester fibers. The dyes of this invention
Disperse dyes from 2-bromo, chloro, or cyano-4,6-dinitroaniline and selected alkyl-3-(2'-alkoxy-5-alkanoylaminoanilino)butyrate or alkyl-4-(2'-alkoxy-5'-alkanoylaminoanilino)valerate
-
, (2008/06/13)
This invention concerns certain substituted aniline coupled dyes, and, in particular, disperse dyes from 2-bromo, chloro, or cyano-4,6-dinitroaniline and selected alkyl-3-(2'-alkoxy-5'-alkanoylaminoanilino)butyrates and alkyl-4-(2'-alkoxy-5'-alkanoylaminoanilino)valerates. These dyes impart bright, blue shades with excellent colorfastness to polyester fibers, and have excellent dyeing properties by either heat fixation or exhaust (boil and pressure) methods of application on polyester fibers. These dyes are also useful for dyeing cellulose ester fibers and polyamides such as nylon.
