Abstract

1390093 Preparing dichloroquinacridones SANDOZ Ltd 16 May 1972 [19 May 1971] 22872/72 Heading C4P Mixtures of 3,10-, 1,10- and 1,8-dichloroquinacridones are prepared by cyclizing 2,5-di- (3<SP>1</SP>-chlorophenylamino)-terephthalic acid with 75-90% sulphuric acid at 100-170‹ C. Processes using 80-88% sulphuric acid at 110- 150‹ C. are preferred. The pigments are used to colour plastics, e.g. viscose, cellulose, acetate, polyethylene, polystyrene, p.v.c. synthetic leather and synthetic latices, paper, surface coatings and printing inks.
