| 摘 要： | 通过实验确定活性黑RL染料的合成工艺。本文采用γ酸重氮化后,在低温酸性条件下与1-(4-磺酸基苯基)-3-羧基-5-吡唑啉酮偶合,2,5-二甲氧基对位酯重氮化后与上述产物进行第二次偶合,偶合产物经Cu络合后盐析、干燥得到活性黑RL染料成品。最佳工艺条件为:重氮反应温度控制在0～5℃、偶合反应时pH=7.5～8、Cu络合反应时温度控制在110℃、pH=6～6.2。 |

| Abstract: | The synthesis technology of reactive dye RL was introduced.Firstly,γ-acid was diazotized,coupled with 1-（4-sulphophenyl）-3-carboxyl-5-pyrazolone in low temperature and at acid condition.Secondly,2,5-dimethoxy para-ester was diazotized too,then coupled with the coupling products above again.Thirdly,secondary coupling products after copper-complexing,salting-out,drying,thus reactive dye RL was got.The optimum process conditions： diazotized at 0~5 ℃,coupled at pH=7.5~8,copper-complexing at 110 ℃,and pH=6~6.2. |
