Pyridine → 1-Amino-2,4-di-n-dodecylaminoanthraquinone

Participants

Reaction Steps

A reactor was charged with 19 g of 1-amino-2,4-dibromoanthraquinone, 28 g of dodecylamine, 0.4 g of copper acetate, 5 g of potassium acetate and 40 g of pyridine and the reaction was effected at an elevated temperature of 115°-120° C. for 20 hours under stirring. The reaction product was dissolved in benzene and insoluble matters were separated, followed by distillation of benzene and recrystallization from glacial acetic acid. A blue solid of 1-amino-2,4-di-n-dodecylaminoanthraquinone was obtained by the reaction of the following formula: ##STR8##
