2-Carboxyphenylhydrazine hydrochloride Use and Manufacturing
Add 6.85g of anthranilic acid and 10ml of water to make a paste, slowly add 12.5ml of concentrated hydrochloric acid, cool to 0°C, add 3.5g of sodium nitrite aqueous solution for diazotization. Then add a solution of 25.5g sodium sulfite in 100ml water below 10°C, stir the reaction, then add glacial acetic acid and zinc powder to stir the reaction and place it at room temperature for 20min, heat in a boiling water bath for 2h, filter, cool the filtrate to room temperature, add concentrated hydrochloric acid to acidify, The precipitate is separated out and filtered to obtain o-hydrazinobenzoic acid hydrochloride.
