Reaction Steps
A mixture of 22 grams (0.2 mole) of benzenethiol, 25.6 grams (0.2 mole) of potassium carbonate in 100 milliliters of dimethyl formamide was heated with stirring to 120° C. for 2 hours. The cooled mixture was added to a cold mixture of 36.6 grams (0.1 mole) of 1,5-dichloro-4,8-dinitroanthraquinone in 150 milliliters of dimethyl formamide, and stirred for 3 hours at room temperature. After addition of 25.6 grams (0.2 mole) of p-hydroxybenzenethiol in 100 milliliters of dimethyl formamide, the mixture was stirred at 125° C. for 2 hours. The resulting reaction mixture was then cooled, and poured slowly into 2 liters of water. Subsequently, the above solid product III was filtered, washed once with water, acetic acid, methanol, respectively, and then dried in vacuo. The yield of this dye was 50 grams (75 percent), m.p. >340° C.; vis (DMF), λmax 540 nm (ε 12,000); Analysis Calculated for C38H24O4S4 : C, 67.83; H, 3.59; O, 9.51; S, 19.06. Found: C, 67.51; H, 3.89; O, 9.35; S, 19.32.
