実験手順

To 120.0 g of polyphosphoric acid (116%) was added with stirring 20.0 g (57.4 mmol) of 2,5-bis(phenylamino)terephthalic acid. The stirred mixture was irradiated in the microwave oven for 1.5 minutes. The reaction mixture was cooled to 80° C. and added with stirring to 1.0 liter of water. The resultant slurry was stirred for 30 minutes, after which the solid component was collected by filtration and washed with 6.0 liters of water. The presscake was dried overnight in an oven at 60° C. to give 17.9 g of crude quinacridone (C. I. Pigment Violet 19) (100% yield).
