| titleOfInvention | Method for producing reductive direct black BCN raw dye |
| abstract | A method for producing reductive direct black BCN raw dye comprises the following steps: a. brominating BO (bromine) in a non-organic solvent and a non-inorganic acid to obtain purple anthrone bromide; b. performing solid phase reaction, and performing condensation reaction on the purple anthrone bromide and 1-amino anthraquinone under the action of a catalyst and an acid binding agent to obtain a crude reductive direct black BCN dye; and c. acidifying the crude reductive direct black BCN dye and removing impurities to obtain the reductive direct black BCN raw dye. The method has the advantages as follows: firstly, in the BO brominating process, any organic solvent or any inorganic acid is not used, only an oxidant is added into water, and the bromination speed is high; secondly, the condensation reaction does not need any solvent and can be finished by heating in a solid phase container, so that the condensation reaction is very safe and environment-friendly; and thirdly, after the crude dye is acidified and copper is removed, the heavy metal content meets an ETAD requirement. |
