Abstract

1,131,084. Anthraquinone dye. SANDOZ Ltd. 16 Feb., 1966 [5 March, 1965; 18 March, 1965], No. 6780/66. Heading C4P. [Also in Division D1] In Example 1 the disperse dye 1-(2<SP>1</SP>-ethoxycarbonyl - ethylamino) - 4 - cyclohexylaminoanthraquinone is prepared by treating 1-amino- 4 - cyclohexylaminoanthraquinone with acrylic acid amide and sulphuric acid to give 1-(2<SP>1</SP>- carboxyethylamino) - 4 - cyclohexylaminoanthraquinone which is then esterified with ethanol and 100% sulphuric acid.
