Preparation method of isocoumarin dichloride

A preparation method of vat violet 1 belongs to the technical field of dye preparation. The preparation method comprises: adding isoviolanthrone, water and sulfuric acid to a container in sequence, performing grinding and pulverization, adding halogenated alkane to the ground mixture, adding a chloridizing agent below the liquid level, adjusting the pH value till the obtained solution is neutral,raising the temperature of the adjusted mixture till the mixture undergoes reflux, performing filtration till halogenated alkane is totally evaporated, cleaning the filtered cake with hot water till the filtrate is colourless, taking the filtered cake out, and drying the filtered cake to obtain vat violet 1. According to the technical scheme, defects that a large amount of solvent is hard to recycle and causes pollution due to a full-solution chlorination method are overcome. The synthesized vat violet 1 is a bright-colored red purple vat dye, is more bright gorgeous than a product sold in themarket, and is high in intensity of raw powder.
