Development of Reactive Blue Dyestuffs with Bi-functional Reactivity

Diazotization of STA synthesized by the indirect diazotization method. The effect of catalyst and agitation (rpm) about STA and H-acid reaction were examined and the optimum conditions were investigated experimentally. The yields and characteristics of 1ㆍst coupling and diazotization synthesis were identified by HPLC and FT-IR analysis. 1ㆍst condensation of CNC and mPDSA were synthesized at 5℃ and pH=6.5. The conditions of alkaly coupling of H-acid were synthesized at 5℃ and pH=8. The condensation of products was identified by U. V. analysis. From this results, It was obtained to reactive dyestuffs of bi-funtional reactivity with high fastness and high adsorption.
