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.
