| titleOfInvention | Preparation of Arylaminohydroxyanthraquinones |
| abstract | The present invention uses an amine of Formula 3 in an amount of 10 to 100% excess of amine based on 1 mole and 1 mole of amine per one chlorine atom in the compound of Formula 2, and the alkali metal and alkaline earth metal carbonate, alkali metal A chlorohydroxyanthraquinone of formula (II) with an amine of formula (3) is characterized in that the reaction is carried out in an inert solvent in the presence of a base selected from the group consisting of acetates, phosphates of alkali metals and any mixtures thereof. Reaction provides a process for preparing arylaminohydroxyanthraquinone of formula (1).n n n <Formula 1>n n n n n n n n Wherein R 1 , R 2 , R 3 and R 4 are independently hydrogen, hydroxyl or NH-Ar, wherein Ar is an aryl radical optionally substituted with one or more substituents, identical or different, with the proviso that R 1 to at least one of R 4 is OH and at least one of R 1 to R 4 is NH-Ar Im)n n n <Formula 2>n n n n n n n n (Wherein, R 5, R 6, R 7 and R 8 are independently hydrogen, are chlorine or hydroxyl, with the proviso that R 5 to R is at least one of 8-chlorine, R 5 to R 8, at least one of the hydroxyl Lock room)n n n <Formula 3>n n n H 2 N-Arn n n Wherein Ar is as defined above. |
