Abstract
Linear-trans-quinacridones are made by heating a 2: 5-dianilinoterephthalic acid with phosgene in the presence of an organic compound which is inert and liquid under the reaction conditions or a mixture of such compounds to a temperature of about 140 DEG to 250 DEG C. Organic compounds specified are nitrobenzene, trichlorobenzene, naphthalene and N-methylpyrrolidone. The terephthalic acid may contain one or more halogen, alkoxy or alkyl substituents on the anilino, radicals. Specifications 896,803, 924,661, 924,662 and Belgian Specifications 579,525, 583,317 and 586,007 are referred to.
