Production methodprocess of Fluorescent Red GG powder

Take 3-bromobenzanthrone and o-aminothiophenol as raw materials, first condense them, then diazotize their amino groups, and then close the ring to obtain Fluorescent Red GG powder.

1. Add 12.4g of 3-bromobenzanthrone, 6.5g of o-aminothiophenol, 100ml of dimethylformamide (DMF) and appropriate amount of sodium carbonate to the reaction flask, protected by nitrogen, and the temperature was raised to 90°C. The reaction was carried out to the end point. Cooled to room temperature filtration, washing, drying to condensation intermediate 3-(2'-aminophenylmercapto)benzene bypass anthrone to be used.
2. Add 3-(2'-aminophenylmercapto)benzanthrone 7.0 g, N-methyl pyrrolidone 100 ml, 3.0 g of concentrated sulfuric acid in the reaction flask, cooled down to 5 ℃, dropwise addition of aqueous sodium nitrite, added within 30 min, continue to stir the reaction to the condensation intermediate disappeared. Then add a small amount of CuSO4, raise the temperature to 110 ℃, the reaction to the end point. Cooling, filtration, washing, drying to obtain purplish red powder Fluorescent Red GG CAS 16294-75-0 .
