ВЕРОЯТНЫЙ МЕХАНИЗМ ОБРАЗОВАНИЯ 2-ХЛОРФЕНИЛ-АЗО-4-ГИДРОКСИФЕНИЛ-КАРБОКСИ-3

A new method for the synthesis of new compounds based on substituted azophenols containing atoms of different positions of electron-acceptor and electron-donor substituents has been studied. The technological process has been developed, the installation consists of one technological line, the process is periodic. The synthesis of highly effective azo dyes is used in almost all sectors of the economy, in particular, in the engineering, chemical and pharmaceutical industries for dyeing natural, synthetic polymers, fibers, as well as for dyeing tablets.
