YieldReaction ConditionsOperation in experiment
46.7% With sodium amide In N,N-dimethyl acetamide at 162.5 - 165.5℃; for 10 h; Inert atmosphere In advance the flake raw materials of sodium amide into powder, grinding process should pay attention to prevent sodium sesame absorption;20 g of fluoranthene, 10 g of powdered sodium amide, 60 g of N, N-dimethylacetamide were added to the first reaction vessel,Using nitrogen protection, slowly warming to 164 ± 1.5 ,And the mixture was stirred for 10 hours to obtain a mixed solution containing indene perylene in dark blue and black,Heating and heating process kept stirring;The mixed solution containing indene perylene was cooled to 10 ° C, and 60 g of absolute ethanol was slowly added dropwise to the mixed solution containing indene perylene. The temperature of the solution was less than or equal to 20 ° C, and the temperature of the solution to be mixed was not increased , Then slowly add 80g water, resulting in deep red solid precipitation, dripping process temperature ≤ 20 , room temperature stirring 6h, filter, filter cake washed to neutral,Dried at 80 for 6h to obtain 15 g of crude indene perylene, the yield was 75.7percent.After the crude indene perylene was pulverized into a powder,Was added to the second reaction vessel, 150 g of toluene was added, and the mixture was heated to toluene and maintained in a reflux state for 3 hours. The filter cake was dried at 80 ° C for 4 hours to obtain 6 g of the first material in the form of a magenta solid powder in a yield of 40 percent. The content of indene perylene was 96.2percent by liquid phase.The first material was added to the third reaction vessel, 90 g of toluene was added, the mixture was heated to toluene and refluxed for 3 hours. The filter cake was dried at 80C for 4 hours to obtain 2.8 g of a second material having a magenta solid powder , The yield was 46.7percent. The content of indene perylene was determined by liquid chromatography to be 98.4percent.
