表面活性剂对C.I.活性蓝221的增溶作用

分别以NaCl、AEO9、AEO3、JFC、AES和L-64为添加剂，研究了它们对C.I.活性蓝221在25 ℃水中的溶解度的影响。实验结果表明，NaCl的加入会大幅降低染料的溶解度；而五种表面活性剂对染料都有增溶作用，增溶效果依次为：JFC（L-64）>AEO9>AEO3>AES。当JFC或L-64用量为80 g/L时，可使C.I.活性蓝221的溶解度由空白时的100 g/L提高至190 g/L。以JFC，L-64，AEO9为混合助溶剂时，当溶液中含有15 g/L JFC， 20 g/L L-64和5 g/L AEO9时，C.I.活性蓝221的溶解度可以提升至200 g/L，染料溶液稳定时间达20 h以上。

Solubilization effect of some surfactants on C.I. Reactive Blue 221

The solubility of C.I. Reactive Blue 221 in water was investigated at 25 oC using NaCl, AEO9, AEO3, JFC, AES and L-64 as the additives respectively. The results show that: the addition of NaCl will decrease the solubility significantly；while the surfactants improve solubility of C.I. Reactive Blue 221 to a certain degree. The solubilization effects of the five surfactants were followed by JFC ( L-64 ) >AEO9 > AEO3 > AES. When AEO9 or L-64 was added as a dosage of 80 g/L, the water solubility of C.I. Reactive Blue 221 was improved from 100 g/L to 190 g/L. When 15 g/L JFC, 20 g/L L-64 and 5 g/L AEO9 were added as the combination additives in the solution, the solubility of C.I. Reactive Blue 221 went up to 200 g/L, and the stability time of the liquid reactive dyes prepared was more than 20 hours.
