Process for the preparation of fibre-reactive non-chromophoric amines

摘要

A novel process for the preparation of compounds of the formula <IMAGE> consists in reacting compounds of the formula <IMAGE> with reactive components of the formula X-L, where the radicals X, R, B, Z and L have the meaning indicated in the description, in aqueous medium in the presence of an alkali metal fluoride-free buffer for the eliminated H-X at pHs above 3 in such a way that the reactive component is added without an additional pH regulation taking place in the course of this process.
