실험 절차

Using a Venturi nozzle, per hour a solution of 300 g of dimethyl 2,5-dianilino-3,6-dihydroterephthalate and 400 ml of N,N-dimethylformamide was nozzled into a preheated gas stream of nitrogen (1.2 m3 /h) and air (300 l/h) at 500° C. This gas-liquid mixture was introduced tangentially into a tubular reactor (50 mm in diameter, 400 mm in length) at 575° C. A conventional workup gave 224 g of crude quinacridone per hour of 98% purity (according to UV).
