Synthesis method

Using o-aminoanisole as raw material, it is first acylated with acetic anhydride, chlorosulfonated with chlorosulfonic acid, condensed with diethylamine, and then hydrolyzed with sodium hydroxide. Raw material consumption (kg/t) o-acetamidoanisole (100%) 425 diethylamine (100%) 180 chlorosulfonic acid 1800 caustic soda (50%) 170 hydrochloric acid (31%) 120

Purpose

It is mainly used for dyeing and printing cotton and viscose fabrics. It is the only light pink light-fast dye among ice dyes. It can replace soluble reduced pink IR (indigosol pink IR) and bright red base. It can also be used for printing and dyeing silk and nylon fabrics.
