Chem. Res. Div., Korea Adv. Inst. Sci. Technol., Seoul, S. Korea). Han'guk Somyu Konghakhoechi, 20(5), 282-90 (English) 1983. CODEN: HSKCDQ. ISSN: 0253-6420. DOCUMENT TYPE: Journal CA Section: 41 (Dyes, Organic Pigments, Fluorescent Brighteners, and Photographic Sensitizers) Scarlet bifunctional reactive dye I [88452-52-2] was synthesized and its reactivity, as detd. by the alk. hydrolysis rate const., and its dyeing properties on cotton were studied. The pseudo-first-order rate const. 16452-06-5 and 2494-89-5 which are cas registry numbers of chemicals are mentioned. of I at 60° and pH 10 was 8.3 ′ 10-3 min-1, compared with 1.3 ′ 10-1 and 4.4 ′ 10-4 min-1, resp., for analogous dyes in which the p-HO3SOCH2CH2SO2C6H4NH group was replaced by Cl or NEtPh. The color yield of I (78%) changed very little in the 50-80° range, and the fastness properties were all within com. acceptable limits. .
