Abstract: A process for controlling and optimizing chemical industrial processes for the preparation of dyes, fluorescent whitening agents and their intermediates, which process comprises controlling and optimizing those processes by differential analysis of the UV/VIS absorption spectra of at least one starting compound and of at least one reaction product. The advantage of this process is that the actual state of a process can be constantly measured, assessed, and used for feed-back and feed-forward control.

Abstract: The invention relates to a process for the preparation of the dyestuff Direct Yellow 11 directly in the form of stable concentrated solutions, in which caustic soda in aqueous solution is reacted, at a temperature from 40.degree. to 90.degree. C., with a solution containing 4-nitro-toluene-2-sulfonic acid, one or more alkanolamines, one or more alcohols containing an etheroxide function or a second alcohol function, then the caustic soda is neutralized by addition of sulfuric acid and the sodium sulfate thus formed is separated by filtration. The solutions obtained by the process according to the invention are particularly suitable for dyeing cellulosic materials and leather.
