1,4-BIS(METHYLAMINO)ANTHRAQUINONE - Uses and synthesis methods
introduction
disperse blue 14 is also called transparent blue GP and solvent blue 78. its chemical name is 1,4-bis (methylamino) anthraquinone, its English name is SolventBlue78, its molecular formula is C16H14N2O2, its molecular weight is 266.29, and its CAS number is 2475-44-7. The appearance is blue-black powder, insoluble in water, soluble in methanol, ethanol, glacial acetic acid, nitrobenzene, pyridine and toluene. It is reddish brown in concentrated sulfuric acid.
application
solvent blue 78 can be used for coloring various resin plastics, such as polyacrylic resin, ABS resin, polystyrene, plexiglass, polyester resin, polycarbonate, etc., to obtain red blue; It can also be used to manufacture fireworks, with excellent heat resistance, sun resistance and migration resistance, good tinting power, high transparency and wide application range.
Preparation
A method for producing a low-pollution diarylamine anthraquinone solvent blue 78 dye, which includes the following steps:
(a) add 800kg of methanol and 800kg of N-methylimidazole to the reaction container in sequence, then slowly add 1200kg of 4-bromobutyric acid under stirring and cooling, slowly add 50% sodium hydroxide solution to pH>9 under stirring and cooling at 50 ℃, then add 50kg of fluoroboric acid, dissolve for 5 hours and then remove methanol under reduced pressure to obtain the first mixture;
(B) raise the temperature of the above-mentioned first mixture to 50 ℃, add 1200kg of 1,4-dihydroxyanthraquinone, 300kg of 1,4-dihydroxyanthraquinone leuco and 580kg of monomethylamine, stir evenly and then continue to raise the temperature to 55 ℃ to reach the end point; Use HPLC detection to determine the end point of the reaction; Then cool down to 35 ℃, open the bottom valve;
(c) wash the filter cake with 500kg of hot water, collect the washing liquid and filtrate, and carry out distillation to recover the solvent; Then wash the filter cake with 90-100 ℃ hot water to neutral, and obtain 1582kg of dispersed blue 14 finished product after drying, crushing and packaging; The yield is 95.1%. △ C2.714 is bright and the pressure value is 0.23.
