摘要
A new process for the production of reactive dyes by the reaction of cyanuric chloride with anionic dyes containing an amino group, which process comprises the adiabatic reaction of cyanuric chloride with the dye, at a temperature of 20° to 80° C. and a pH value of between 3.0 to 7.0, with the rapid addition of the educts within 1 to 30 minutes, produces reactive dyes in good yield and purity and is technically advantageous.
