| titleOfInvention | A kind of reactive yellow dyes of high washing fastness and preparation method thereof |
| abstract | The invention discloses a kind of reactive yellow dyes of high washing fastness and preparation method thereof, m-phenylene diamine (MPD) is acylated urea acylamino- aniline between generation with Zassol in acid condition, with 3, 6, the diazol of the naphthylamines of 8 trisulfonic acid 2 is coupled to obtain color base, color base carries out primary condensation with Cyanuric Chloride, again with by antifebrin and chlorosulfonic acid, thionyl chloride reaction generation N-acetylsulfanilyl chloride, carry out being condensed to obtain thioether with the sulfide of 2 chloroethylamine hydrochlorides and mercaptoethanol reaction generation, thioether is reoxidized, obtained 2 [2 (4 aminobenzene sulfonamide base) ethyl sulfuryl] the hydroxide ethylsulfuric acid ester intermediates of esterification carry out secondary condensation, filtering, collect filtrate, Direct spraying it is dry semi-finished product.Reactive yellow dyes of the present invention have direct high, compatibility good, and lifting force height, degree of fixation are high, and every fastness is excellent；Suitable for the dyeing of cellulose fibre, protein fibre, viscose rayon and Fypro, stamp and pad dyeing, washing fastness is higher than 0.5 1 grades of general kind. |
