摘要：

The one-pot synthesis of some azo disperse dyes were carried by heating of aniline, sodium nitrite, potassium hydrogen sulfate with active methylene compounds under focused microwave heating in absence of the solvent. Also, by heating of diazoaminobenzene with active methylene in acetic acid solution, in the presence of few drops of hydrochloric acid, were described. Syntheses of novel heterocyclic aromatic compounds as potential intermediates for preparation of azo disperse dyes were studied. The dyeing of polyester fabrics with disperse dyes by the use of high-temperature dyeing method at 130 degrees C and carrier dyeing method were also used. (C) 2008 Wiley Periodicals, Inc.
