Abstract
Quinacridone is precipitated from a polyphosphoric acid solution thereof by dilution with an organic, water-miscible liquid, the said solution being prepared otherwise than by the ring-closure of a 2:5-diarylamino-terephthalic acid by heating with at least an equal weight of a polyphosphoric acid having an orthophosphoric acid equivalent of at least 105%. The solution may first be diluted with water or dilute orthophosphoric acid. Organic liquids specified are methanol, ethanol, isopropanol, glycerol, diacetone alcohol, diethylene glycol, acetone or mixtures thereof with water, or a mixture of denatured alcohol, ethyl acetate and aviation gasoline. Examples are given in which the solutions are made by dissolving quinacridone in polyphosphoric acid. Specifications 828,051, 828,052 and 884,044 also are referred to.
