摘要：The condensation reaction between C.I. Reactive Red 120 and m- and p-(beta-sulfatoethyl-sulfonyl)aniline has been studied using the TLC-double scanning method. The condensation reaction follows a consecutive reaction route, and the rates of the first-step reaction (k(1)) are about twice as fast as those of the second-step reaction (k(1)) The rate constants of the two step reaction (k(1) and k(2)) vary with reaction temperature and pH. The rate constants of the condensation reaction between m-(beta-sulfatoethyl-sulfonyl)aniline and C.I. Reactive Red 120 are about 10 times greater than for p-(beta-sulfatoethyl-sulfonyl)aniline.
