Reaction Steps
The pleochroic dye 1-butylphenylamino anthraquinone was prepared by dissolving 1-chloroanthraquinone in a 10-fold excess of 4-n butylaniline. Copper acetate and sodium acetate were added as in Example 70. Since the n-butylaniline is a solvent in this case no nitrobenzene was added. The dye, when tested as in Example 70, had an absorption maxima at 515 nm and an order parameter of 0.65.
