| titleOfInvention | A kind of synthetic method of Azo type disperse dye composition |
| abstract | The present invention relates to technical field of disperse dyes, for solving 2, 4-dinitraniline easily causes the general dissatisfactory problem of the light fastness of its monochromatic kind, the present invention proposes a kind of synthetic method of Azo type disperse dye composition, the diazo component 2 of component each in required mixture, 4-dinitraniline reacts simultaneously in same diazotization equipment, during coupling, diazonium carries out coupling by multiple coupling manner according to ratio requirement each coupling component of mixing colouring agent in same coupled device, the coupling solution obtained can carry out intensification if needed and turn brilliant process before entering strainer, make the crystalline form of the dyestuff obtained relatively stable, then press filtration directly obtains the dye mixture of required proportioning, not only solve the problem of light fastness, and turn brilliant process warm and, the high/low temperature dispersion stabilization of dyestuff and coloured light are comparatively stable. |
