Abstract
The hydrolysis behaviors of C.I. Reactive Orange 13(0-13). C.I. Reactive Orange 16(0-16) and C.I. Reactive Red 194(R-194) which contain monochlorotriazine(MCT), sulfatocthylsulfone(SES) and monochlorotriazine/sulfatoethylsulfone(MCT/SES) as functional groups, respectively, were investigated by chromatography(TLC, CC, PC, HPLC) and FT-IR. The hydrolytic behavior of R-194 was similar to that of O-16. but R-194 showed a good resistibility to hydrolysis in aqueolls dyeing solution than O-13 and O-16 due to its bifunctional reactive group.
