Abstract
Cyanuric fluoride was reacted with 1-Amino-8-napnthal-3.6-disultonic acid at 0~6 ℃,pH=1.5~2.0,for 2~2.5 hours to give condensateⅠ.Then,coupled with diazonium salts ofo-Aminobenzenesulfonic acid to give a condensate Ⅱ,Ⅱ was condensed with 4-(2-sulfatoethylsulfonyl) niline to give modified product of C.I Reactive Red 240.These novel reactive dyes containg iso-bifunctional group had good color fastaesses,fixation,leveness,less sensitivity to bath ratio and good reproducdivity,especially excellent wet fastaess.They provide potential values in research and developments.
