Studies on the Syntheses of Reactive Dyes(I) -Syntheses and Application of $\beta$-sulfatoethylamino sulfone reactive dyes-

반응성염료의 합성에 관한 연구(I) -$\beta$-Sulfatoethylamino sulfone형 반응성 염료의 합성과 그의 응용-

Reactive dyes with $\beta$-sulfatoethylamino sulfone as reactive component were synthesized via coupling of p-aminophenyl $\beta$-sulfatoethylamino sulfone with H-acid at pH 4 and 7. It was coupled at 2 prosition of H-acid at pH 4, and 7 position at pH 7. These dyes were identified by IR, UV-visible spectra and quantitative analysis of sulfur. The hydrolysis properties and the effect of salt, alkaline, and pH on dyeing were also investigated.

$\beta$-sulfatoethylamino sulfone을 반응성기로 하는 반응성 염료를aniline을 출발물질로 하여 만든 p-aminophenyl $\beta$-sulfatoethylamino sulfone을 H-acid 와 pH 4 및 7에서 coupling시켜 얻었다. pH 4에서는 H-acid의 2위치에, pH 7에서는 H-acid의 7위치에 coupling되었으며, 이 염료들을 IR, UV-visible spectra, 황분석에 의해서 확인하였다.
