Method for producing 1-amino-2-phenoxy-4-hydroxyanthraquinones

摘要

1-Amino-2-phenoxy-4-hydroxyanthraquinones, which are useful as a red disperse dye for polyester fibers, and also useful as an intermediate for the production of other red disperse dyes, are produced in a high yield and purity by reacting a 1-amino-2-halogeno-4-hydroxyanthraquinone with a phenol compound in a sulfane solvent in the presence of an acid binding agent.
