Abstract

1418925 Nitroanthraquinone BADISCHE ANILIN- & SODA-FABRIK AG 31 Jan 1973 [1 Feb 1972] 4807/73 Heading C2C A process for the continuous production of a nitroanthraquinone mixture containing mainly 1-nitroanthraquinone which process comprises nitrating anthraquinone with nitric acid in heterogeneous phase in from 70 to 90% by weight sulphuric acid at a temperature of from 20‹ to 100‹ C. in a cascade consisting of at least two vessels at superatmospheric pressure. Examples are furnished. The process is described referring to a diagram of the apparatus (not shown).
