In 1-methyl-pyrrolidin-2-one; at 75 - 180℃;Inert atmosphere; | In a nitrogen protection device,Magnetic stirring,And equipped with a spherical condenser trap 250mL three-necked flask,Add 10 g of 5-aminoterephthalic acid and 80 mL of NMP.Under nitrogen protection,Stirred for 30min to obtain a homogeneous solution,Then, 13 g of 4-phenylacetylene phthalic anhydride was added,The solution was heated to 75 ° C for 2h;Then 20g of toluene was added,The reaction was gradually warmed to 180 ° C,The generated water is taken out by the water trap;After 6-8h reaction,Cooled to 120 ° C,The mixed solution was poured into excess deionized water,Suction filtration, washing and drying.That is, 2- (4-phenylethynylideneimide) -1,4-dibenzoic acid was obtained. |
