Abstract

1,160,287. Sulphonated tri- and tetra-anthrimides. RUMANIA,MINISTRYOFCHEMICAL INDUSTRY. 23 Nov., 1966 [16 Dec., 1965], No. 52492/66. Heading C4P. The invention comprises sulphonated 1, 1<SP>1</SP>, 4, 1<SP>11</SP> trianthrimide and 1, 1<SP>1</SP>, 4<SP>1</SP>, 1<SP>11</SP>, 4<SP>11</SP> 1<SP>111</SP> tetraanthrimide. The compounds are prepared by treating the anthrimide with oleum at 100- 130‹ C., followed by dilution of the product to a concentration by weight of 75% and precipitation of the dyestuff.
