Abstract It has been found that the condensation rate of 1-amino-4-bromoanthraquinone-2- sulphonic acid (I) with 1, 3-diaminobenzene-4-sulphonic acid (II) giving 1-amino-4-(3'-amino- 4'-sulphoanilino) anthraquinone-2-sulphonic acid (III) in media of NaHCO 3-CO 2 and NaHCO 3-Na 2 CO 3 with catalysis by CuI obeys the kinetic relation* u= k [I][II][Cu+][CO 2-3], being controlled by the kinetic relation* u= k [I][II][Cu+] 2 [PO 3-4] in media of NaH 2 PO 4- ...
