- Solvent red 59 of the synthesis process (by machine translation)
-
The invention discloses a solvent red 59 synthesis process, in order to 1, 4 - dinitro - 2, 3 - two chloroanthraquinone, phenol sodium as raw materials, the organic solvent in the presence of O-chlorobenzene to generate a condensation reaction to produce 1, 4 - dinitro - 2, 3 - [...] anthraquinone, 1, 4 - dinitro - 2, 3 - [...] anthraquinone and then by further reduction to produce 1, 4 - diamino - 2, 3 - [...] anthraquinone. Because of the 1, 4 - dinitro - 2, 3 - dichloro anthraquinone activity and low 1, 4 - diamino - 2, 3 - dichloro anthraquinone of high activity, the invention the reaction is easy to carry out, so greatly shortens the reaction time; and the reaction less side reaction, high yield, insoluble matter is greatly reduced, while at the same time, this synthetic route will not produce a large amount of salt-containing waste water, the process is relatively clean and environmental protection.
