Reaction Steps
90 parts of 2,2-dimethyl-1,3-hexanediol, 27.3 parts of 1-amino-4-hydroxy-2-chloroanthraquinone, 45 parts of N-methylpyrrolidone, 9.4 parts of phenol and 12 parts of potassium carbonate are heated for 5 hours at 130°C and 8 hours at 140°C under nitrogen. When cold, the mixture is diluted with 140 parts of methanol and filtered. The filtrate is diluted with water. 21 parts of 1-amino-2-(2',2'-dimethyl-3'-hydroxyhexoxy)-4-hydroxyanthraquinone are obtained.
