“…Unsymmetrical disazo 36 and trisazo 37 was applied as acid and direct dyes on wool and cotton fabrics. They had fairly good washing fastness but unsatisfactory tinctorial strength and light fastness below average was monitored [36] The fusion of 3(and 4)-nitrophthalic anhydride with aniline gave 3(and 4)-nitro-1-Nphenylphthalimide [37,38] which was exposed to reduction using tin(II) chloride and hydrochloric acid to afford the corresponding amino derivatives 38 [39] and 39 [40]. Compound 40 was condensed with 38 and 39 respectively, by refluxing for 8 hours in dry xylene and in addition to a drop of piperidine, to give 41 and 42.…”

I MPORTANCE of heterocyclic dyes has recently increased due to their deep shades, high tentorial strength, excellent colorfastness and brightness compared to azobenzene analogous. Development of novel synthetic approaches for fused heterocyclic dyes has remained a highly interesting but challenging proposition. An overview of the application of nitrogen-containing fused heterocyclic dyestuffs for textile coloration is presented. In this review, we provide details outlining the synthesis of recently prepared fused nitrogen-containing heterocyclic dyestuffs and their dyeing efficiency on textile fibers.

columns were analyzed grav¡metrically using. 2 -mercaptobenzothiazole (2) (Table I). Preliminary experiments of a similar kind had shown the necessity of leaching the ignited iridium precipitate in boiling 1 to 1 hydrochloric acid, prior to reduction in hydrogen, to eliminate contaminants that follow iridium through the cation exchange columns. This problem has been noted by Tertipis and Beamish (11).
