Synthesis method

Use hydroquinone as raw material, alkylate with ethyl chloride, then nitrate with nitric acid, reduce with sodium sulfide, and then use benzene Formyl chloride is acylated, then nitrated with nitric acid, reduced by pyridine and sodium bisulfite, and refined, filtered and dried. Raw material consumption (kg/t) Hydroquinone (98%) 560 Nitric acid (98%) 930Ethyl chloride (95% ) 930 Hydrochloric acid 710 Benzoyl chloride (98%) 630 Sodium sulfide (63.5%) 1040Pyridine (98%) 32 Sodium bisulfite (95%) 1030Caustic soda (100%) 970 Ammonium chloride (98%) 70 Pure carbon (98%) 700 Zinc ingot 110

Purpose

Mainly used as a developer for dyeing and printing cotton, viscose and silk fabrics, and is more suitable for resist dyeing printing. It is less used for dyeing alone and is not easy to remove the dye.
