<p>A process for producing 1-aminoanthraquinones represented by formula (C) <CHEM> wherein R<1> and R<2>, independently from each other, denote one type selected from a hydrogen atom, an alkyl group having 1 to 4 carbon atoms and a halogen atom, which comprises converting 5-nitro-1,4,4a,9a-tetrahydroanthraquinones represented by formula (A) <CHEM> wherein R<1> and R<2> are as defined above, into 1-hydroxylaminoanthraquinones represented by formula (B) <CHEM> wherein R<1> and R<2> are as defined above, in the presence of a basic compound, and electrolytically reducing the resulting 1-hydroxylaminoanthraquinones in the presence of a basic compound.</p> |
