摘要：Two model reactive dyes containing two vinyl sulfonyl groups were synthesized. The reactions between two vinylsulfonylanilines and a model dye have been studied in DMF at 90 +/- 1 degrees C respectively and the rate constants of the reactions were determined by the Thin Layer Chromatograph scanning method. It was found that the rate constant of the reaction of 3-vinylsulfonylaniline and the model dye was 25 times faster than that of 4-vinylsulfonylaniline. (C) 1997 Elsevier Science Ltd.
