Sodium Hydroxide → 1-Amino-2-p-n-hexadecylphenoxy-4-dodecylanilinoanthroquinone

Participants

Reaction Steps

A mixture of 56 g of 2-bromo-1-amino-p-dodecyl-anilino-anthraquinone, 10 g of caustic soda powder and 700 g of p-n-hexadecylphenol was heated at 170°-175° C. for 4 hours. Then, 2000 g of a 5% aqueous solution of caustic soda were added thereto, and the resulting blue precipitate was recovered by filtration, washed sufficiently and dried to yield 1-amino-2-p-n-hexadecylphenoxy-4-dodecylanilinoanthroquinone. The reaction is expressed by the following formula: ##STR11##
