摘要：Dye containing two m-(2-sulfatoethyl sulfonyl) anilino groups was synthesized and characterized. The reaction between m-(2-sulfatoethyl sulfonyl) aniline and the monochlorotriazinyl dye has been studied in aqueous solution at various temperatures and pH values, and the rate constants of the reaction determined by the thin layer chromatograph scanning method. The temperature dependence of the rate constants was normal, but an unexpected increase of the rate constant was observed at pH 2.0. (C) 1998 Elsevier Science Ltd. All rights reserved.
