実験手順

A suspension of 200 g of dimethyl 2,5-dianilino-3,6-dihydroterephthalate in 1 l of water was introduced by means of a two-material nozzle and 1.5 m3 of nitrogen into a tubular reactor (50 mm in diameter, 300 mm in length) at 395° C. Using a solids filter, 170 g of dihydroquinacridone (purity 95%, includes about 3% of quinacridone) were obtained.
