Versuchsvorschrift

A mixture (one part) of 2,5-dianilino-terephthalic acid (80 wt. %) and 2,5-dianisidino-terephthalic acid (20 wt. %) was dissolved in polyphosphoric acid (6.14 parts at 118.5%). The solution, already at 110° C., was heated to 130° C. for 3 hours, cooled to 100° C. and diluted to a fluid mass with water (0.5 parts). The solution was drowned into methanol (11.6 parts) and heated at 120° C. for 4 hours. A very bluish, transparent quinacridone pigment was obtained.
