| titleOfInvention | A dye synthesis making method for a distillation under reduced pressure |
| abstract | The present invention relates to a dye synthesis method using a distillation under reduced pressure, and more particularly, an aqueous solution reaction step consisting of a diazo reaction process, a coupling reaction process, and a chromic process, which is a general synthesis process of yellow 59 in a metal complex salt acid dye. In the dye synthesis method through a solvent / aqueous reaction step consisting of a croaming reaction step and a filtration step, in the solvent / aqueous reaction step, instead of the croaming reaction step and the filtration step, a vacuum pressure distillation step and a washing step are introduced to the solvent / aqueous solution step. The characteristics of the present invention are to reduce the amount of toxic wastewater generated by the use of the organic solvent in the aqueous solution reaction step, but to synthesize a high-quality dye having the same or similar purity as the dye by the conventional process. have. |
