1,4-二氨基-2-氯蒽-9,10-二酮

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A solution of dimethylsulfoxide (50 ml), water (5.0 ml), 2-chloro-1,4-diamino anthraquinone (5.0 g) and sodium hydroxide (1.0 g) is heated to 100° C. for 4 hours. The mixture is cooled and diluted with water until a precipitate forms. The precipitate is collected, washed, dried and recrystallized from carbon tetrachloride. The yield is 24 percent 2-(p-hydroxy ethyl phenoxy)-1,4-diamino anthraquinone with a melting point of 224° C. to 227° C. The mixture is cooled The precipitate is collected washed dried recrystallized from carbon tetrachloride

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A mixture of thionyl chloride (320 g) and 1,4-diamino anthraquinone (20 g) is refluxed for 24 hours. The mixture is then cooled and poured onto crushed ice. The precipitate is filtered, dried and purified by recrystallization from carbon tetrachloride. The yield is 50 percent 2-chloro-1,4-diamino anthraquinone with a melting point of 207° C. to 210° C. is refluxed for 24 hours The mixture is then cooled poured onto crushed ice The precipitate is filtered dried purified by recrystallization from carbon tetrachloride
