| production method | with 1-aminoanthraquinone and β-(4-hydroxy-3-methyl)-Methyl phenyl propionate as raw material. First, 1-aminoanthraquinone is halogenated (chlorinated or brominated) and hydrolyzed to give 1-amino-4-hydroxy-2-haloanthraquinone, condensation with β-(4-hydroxy-3-methyl)-phenylpropionic acid methyl ester yields the product. The final product was obtained by filtration, grinding and drying.. |
