1-Amino-4-(3'-Acetaminoanilino) Anthraquinone-2-Sulfonic Acid 합성의 전화율에 미치는 반응조건의 영향

The Effect of Reaction Conditions on the Conversion of Synthesis of 1-Amino-4-(3'-Acetaminoanilino) Anthraquinone-2-Sulfonic Acid

The conversion of 1-Amino-4-(3'-Acetaminoanilino) Anthraquinone-2-Sulfonic Acid prepared by the Ullmann condensation have been investigated as a function of the reaction conditions such as catalysts, initial concentration of reactants, reaction temperature, pH, condensation agents and neutralizing agents. The experimental results showed that the Cu(I)-type catalysts had higher activity than the Cu(II)-type catalysts in this study. The conversion increased with increasing initial concentration of reactants but decreased at above critical concentration owing to agglomeration of reactants. It was also observed that the maximum conversion obtained at 7$0^{\circ}C$ and pH=7~8.
