Versuchsvorschrift

The pleochroic dye 1-cyclohexylphenylamino, 4-hydroxyanthraquinone was prepared by combining equimolar quantities of 1-chloro-4-hydroxy anthraquinone and 4-cyclohexylaniline and heating in the presence of a catalytic amount of copper acetate (0.1 g/0.1 mole) and sodium acetate (10 g/0.1 mole) in nitrobenzene. The reaction was run and the dye separated and tested as in Example 70. The dye had an absorption maxima at 594 nm and an optical order parameter of 0.75.
