Embodiment 1
[0035] Add 0.001mol (0.2232g) 1-aminoanthraquinone, 0.020mol (5.0850g) 4,4′-difluorodiphenyl sulfone and 0.0011mol (0.1518g) anhydrous potassium carbonate to a device equipped with mechanical stirring, thermometer, with water In the three-necked flask of the condenser and the condenser, nitrogen protection, 28 mL of sulfolane (TMS) was used as the reaction solvent, the solid content was 20%, and 10 mL of toluene was used as the aqueous agent. Bring water at 140°C for 3 hours, distill out toluene, then gradually heat up from 140°C to 200°C at a rate of 10°C / hour, and stay at 200°C for 2 hours. Heating was stopped, cooled to room temperature, 0.019 mol (3.5380 g) of 4,4'-biphenol and 0.0209 mol (2.8842 g) of anhydrous potassium carbonate were added, and 10 mL of toluene was added again. Bring water at 140°C for 2.5 hours, distill out toluene, then gradually increase the temperature from 140°C to 200°C at a rate of 10°C / hour, and stay at 200°C for 2 hours. Stop heating, when the...
Embodiment 2
[0037] Add 0.003mol (0.6697g) 1-aminoanthraquinone, 0.030mol (7.6275g) 4,4'-difluorodiphenyl sulfone and 0.0033mol (0.4554g) anhydrous potassium carbonate to a device equipped with mechanical stirring, thermometer, with water In the three-necked flask of the condenser and the condenser, nitrogen protection, 43 mL of sulfolane (TMS) was used as the reaction solvent, the solid content was 20%, and 15 mL of toluene was used as the aqueous agent. Bring water at 140°C for 3 hours, distill out toluene, then gradually increase the temperature from 140°C to 210°C at a rate of 10°C / hour, and stay at 210°C for 2 hours. Heating was stopped, cooled to room temperature, 0.019 mol (3.5380 g) of 4,4'-biphenol and 0.0297 mol (2.8842 g) of anhydrous potassium carbonate were added, and 15 mL of toluene was added again. Bring water at 140°C for 3 hours, distill out toluene, then gradually heat up from 140°C to 200°C at a rate of 10°C / hour, and stay at 200°C for 2 hours. Stop heating, when the t...
Embodiment 3
[0039] Combine 0.001mol (0.2702g) 1,5-diamino-4,8-dihydroxyanthraquinone, 0.020mol (5.0850g) 4,4′-difluorodiphenylsulfone and 0.0011mol (0.1518g) anhydrous potassium carbonate Put it into a three-necked flask equipped with a mechanical stirring, a thermometer, a water device and a condenser, nitrogen protection, and use 54 mL of N,N-dimethylacetamide (DMAc) as the reaction solvent, with a solid content of 15%, and 18 mL of toluene as With water. Bring water at 135°C for 3 hours, distill out toluene, then gradually increase the temperature from 135°C to 160°C at a rate of 10°C / hour, and stay at 160°C for 2 hours. Heating was stopped, cooled to room temperature, 0.019 mol (3.5380 g) of 4,4'-biphenol and 0.0209 mol (2.8842 g) of anhydrous potassium carbonate were added, and 18 mL of toluene was added again. Bring water at 135°C for 3 hours, distill out toluene, then gradually increase the temperature from 135°C to 160°C at a rate of 10°C / hour, and stay at 160°C for 2 hours. Sto...
