| titleOfInvention | Multi-active-base red dye with high color fixing rate and high chlorine fastness for printing and preparation method thereof |
| abstract | The invention discloses a multi-active-group red dye with high color fixing rate and high chlorine fastness for printing and a preparation method thereof 1 is-H or-AO 3 H; the R is 2 is-H; x is Cl; m is Na and the preparation method comprises the following steps; (1) preparing a J acid monoazo orange reactive dye; (2) preparing a J acid type disazo red reactive dye; (3) and (3) preparing the multi-active-group red dye g with high color fixing rate and high chlorine fastness. In order to increase the stability of azo bonds in the active red dye chromogen system, 4-beta-ethyl sulfuryl sulfate aniline-2-sulfonic acid and m-phenylenediamine compounds with sulfonic groups at the amino ortho-positions are selected as diazo components, and the azo bond ortho-positions in the final molecular structure of the prepared bis-azo active red dye all have sulfonic groups and can form hydrogen bonds with the azo bonds, so that the stability of the azo bonds is increased, and the azo active red dye can effectively resist the oxidation of effective chlorine in an environmental medium. |
