production method
Using 3-bromobenzanthrone and o-aminothiophenol as raw materials, the two are first condensed, then the amino diazotization, and then the product is obtained in a closed loop..
12.4g of 3-bromobenzinyl anthrone, 6.5g of anthaminothiophenol, 100ml of dimethylformamide (DMF) and appropriate amount of sodium carbonate were added to the reaction bottle, protected by nitrogen, heated to 90 ℃, and the reaction reached the end point. Chilled to room temperature, filtered, washed, and dried to obtain the condensation intermediate 3-(2 '-aminophenyl) benzanthrone for later use.
add 7.0g of 3-(2 '-aminophenyl) benzanthrone, 100ml of N-methylpyrrolidone and 3.0g of concentrated sulfuric acid to the reaction bottle, cool to 5 ℃, add sodium nitrite aqueous solution dropwise, add it within 30min, and continue stirring until the condensation intermediate disappears. Then a small amount of CuSO4 was added, the temperature was raised to 110 ℃, and the reaction reached the end point. Cool, filter, wash and dry to produce purple-red powdery products.
