A reduction olivaceoviridis B dye preparation method

The invention relates to a preparation method of a vat olive green B dye and aims to provide a vat olive green B dye which is simple in process, low in cost and excellent in quality of product, and a preparation method of the vat olive green B dye. The preparation method of the vat olive green B dye comprises the following steps: dissolving 3-bromobenzanthracen and 1-amino-anthraquinone in an organic solvent, adding a catalyst and an acid-binding agent, heating to 200-220 DEG C and carrying out condensation reaction, removing a solvent and filtering, washing a filter cake by using water to be neutral, then drying to obtain anthrimide; dissolving the anthrimide in a triethylene glycol alkaline solvent, reacting for 3-6 hours at the temperature of 150+/-2 DEG C, filtering, washing the filter cake by using water to be neutral, and then drying to obtain a product. The preparation method of the vat olive green B dye is simple in process, short in production cycle, convenient in sources of raw materials, excellent in quality of the produced products and high in yield; meanwhile, the whole production process is low in cost and little in environment pollution.
