中文摘要：采用反相离子对高效液相色谱法（HPLC）研究了双一氟均三嗪活性染料C.I.活性红268在130℃、p H值为7.0~8.0条件下的水解反应及其稳定性。计算了该条件下染料的双一氟均三嗪形式和一氟一羟基双均三嗪形式的水解速率常数k1和k2。130℃下,随着p H值的增大,染料2种形式的水解速率均不断变大,p H值在7.5和8.0下的准一级反应的水解速率常数k1相对7.0而言分别增加了8.8倍和30.2倍。但与70、80℃,p H值为11.0条件相比,高温（130℃）下双一氟均三嗪染料形式和一氟一羟基双均三嗪染料形式在水解反应性上的差距显著减小。作为水解反应的副产物,130℃下染料降解产物的量与80℃时相当,表明母体染料在高温下仍具有较好的稳定性。

外文摘要：Hydrolysis reactivities and stabilities of bis（ monofluoro-s-triazine） reactive dye C. I. reactive Red 268 at 130 ℃ and p H of 7. 0- 8. 0 were studied by reverse-phase ion-pair high performance liquid chromatography（ HPLC）. The hydrolysis rate coefficients of the bis（ monofluoro-s-triazine） form and monofluoromonohydroxybis-s-triazine form of the dye,k1 and k2were calculated,respectively. With the increase of the p H value,hydrolysis rate coefficients of these two forms of the dye kept increasing at130 ℃,and the hydrolysis rate coefficients of the dye raised by 8. 8 times and 30. 2 times,respectively when the p H value increases from 7. 0 to 7. 5 and 8. 0. The difference between hydrolysis reactivity of bis（ monofluoro-s-triazine） form and monofluoromonohydroxybis-s-triazine form of the dye at high temperature（ 130 ℃） decrease significantly,compared with that at 70 ℃ and 80 ℃ and at p H of 11. 0.And as by-product of the hydrolysis reaction,the amounts of degradation products of the dye at 130 ℃are equivalent to that at 80 ℃,which implied good stability for the parent dye at high temperature.
