Synthesis method

The ammoniation method is mainly used. The crude product is obtained by ammoniation reaction between anthraquinone-2,6-disulfonate ammonium salt and ammonia water, which is then filtered and dried. Raw material consumption quota: anthraquinone-2,6-disulfonate ammonium salt (95%) 3381kg/t, 20% ammonia 2150kg/t.


Dye intermediates, mainly used to prepare vat dyes such as vat yellow GCN.
