| Air & Water Reactions | Very soluble in water. Solution is bluish-red. Dilute solutions are strongly fluorescent. | ||||||||||||
| Acidic organic/inorganic salts, such as Rhodamine B, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions. | |||||||||||||

85-44-9 91-68-9 81-88-9 (1) Phthalic anhydride (15.7 g) and 3-(N,N-dimethylamino) phenol (18.0 g) were added to 1,2-dichlorobenzene (57.0 g). The resulting mixture was stirred at 175 °C for 1 hour and then 3-(N,N-diethylamino) phenol (12.1 g) was added in three batches. After the addition was completed, the reaction mixture was continued to be stirred at 175 °C for 12 hours. After completion of the reaction, the mixture was cooled to below 25°C. Subsequently, 3% aqueous sodium hydroxide solution (100 g) was added and stirred for 30 minutes. After separating the organic layer, 4.5% sulfuric acid (330 g) was added and stirred for 30 minutes. After separation of the aqueous layer, 35% hydrochloric acid (30 g) and sodium chloride (15 g) were added and the mixture was stirred at 80 °C for 1 hour. After cooling to room temperature, the resulting crystals were filtered, washed with 2% hydrochloric acid (300 g) and dried at 80 °C to give the compound of [chemical formula Di] (35 g). | |||||||||||||

| Properties and Applications |
| ||||||||||||
| Major impurities are partially dealkylated compounds not removed by recrystallisation.Purify the dye by chromatography, using ethyl acetate/isopropanol/ammonia (conc)(9:7:4, RF 0.75 on Kieselgel G). It has also been crystallised from a concentrated solution in MeOH by slow addition of dry diethyl ether; or from EtOH containing a drop of conc HCl by slow addition of ten volumes of dry diethyl ether. The solid is washed with ether and air dried. The dried material has also been extracted with *benzene to remove oil-soluble material prior to recrystallisation. Store it in the dark.
