| titleOfInvention | A kind of preparation method of active scarlet dye |
| abstract | The present invention relates to a kind of preparation method of active scarlet dye, include the following steps: to be added to Cyanuric Chloride in ice water and carry out mashing processing, obtains mashing liquid；Solid para-ester is added in mashing liquid, mixed ammonium/alkali solutions is continuously added and carries out alkali tune, primary condensation reaction is carried out and obtains a contracting object；The mixed base is soda ash and sodium bicarbonate；Solid J acid is added in a contracting object, condensation reaction is carried out, obtains two contracting things；Continue in the two contracting things for being added to solid H acid, carry out condensation reaction, obtains mixing two contracting things；The molar ratio of the solid J acid and solid H acid is 0.65~0.68:0.32~0.35；Hydrochloric acid is added into Sulpho Tobias Acid and sodium nitrite carries out diazo-reaction, obtains Sulpho Tobias Acid diazonium salt；In the mixing two contracting things that Sulpho Tobias Acid diazonium salt is added to, coupling reaction is carried out, post-processing obtains active scarlet dye.The preparation method is convenient, resource occupation is few, low energy consumption and is easy to mix colours. |
