| 摘 要： | 采用反相离子对高效液相色谱法研究了活性艳蓝KN-R(C.I.活性蓝19)在不同时间、温度、pH值条件下的水解反应。在染料转变为乙烯砜型后,当[OH-]为常数时,该水解反应为准一级反应,水解速率随温度的增加而显著增加。就染料的水解特性而言,活性艳蓝KN-R的最佳应用条件为温度50~70℃,pH值8~9,时间40~80 min。

| Abstract: | The hydrolysis kinetics of vinylsulfone dye,Reactive Brilliant Blue KN-R(C.I.Reactive Blue 19),was studied using reversed-phase ion-pair high performance liquid chromatography(HPLC) under the conditions of varied time, temperature and pH value.After the dyes have converted to vinylsulfone structure,the hydrolysis is a pseudo first-order reaction as long as keeps constant.The velocity of hydrolysis increases with increasing the temperature.In terms of the hydrolysis characteristics,the optimized application conditions for Reactive Brilliant Blue KN-R are as follows: temperature is 50～(70 ℃,) pH value is 8～9,time is 40～(80 min.) |
