実験手順

A mixture (one part) of 2,5-dianilino-terephthalic acid (95%) and 2,5-dianisidino-terephthalic acid (5%) was dissolved in polyphosphoric acid (6.14 parts at 118.5%). The solution, already at 100° C., was heated to 133° C. for 3 hours, cooled and diluted. The solution was drowned into methanol (11.6 parts) and heated at 120° C. for 4 hours. A very bluish, transparent quinacridone pigment, dispersible in an automotive finish, was obtained.
