| Abstract: | The optimum conditions for synthesis of 1 amino 2 bromo 4 hydroxyanthraquinone via cyclical reactions of bromination and hydrolysis from 1 amino 2 bromoanthraquinone are studied. In order to reduce the consumption of bromine, a new technology of synthesis of 1 amino 2 bromo 4 hydroxyanthraquinone from 1 aminoanthraquinone in the presence of boric acid with lower bromine consume is proposed. This technique can be used to prepare other 2 substitued 1 amino 4 hydroxyanthraquinone from corresponding 2 substitued 1 amino anthraquinone. |
