실험 절차

27.7 parts of 1,3-dichloroanthraquinone, 18.15 parts of 2-chloro-4-nitroaniline and 10 parts of sodium carbonate are suspended in 400 parts of o-dichlorobenzene whilst stirring. After adding a solution of 0.4 part of copper-(I) iodide in 5 parts of pyridine and 25 parts of toluene, the mixture is kept at 160°-165° for 5 hours, whilst eliminating the water of reaction. When the mixture has cooled, it is filtered and the precipitate is washed with o-dichlorobenzene, acetone and hot water and extracted by boiling with dilute hydrochloric acid. 29 parts of 1-(2'-chloro-4'-nitroanilino)-3-chloroanthraquinone, which bulk-dyes PES in orange shades of good fastness properties, are obtained.
