ABSTRACT:
A process and an equipment for obtaining dry 1,5- and/or 1,8-dinitroanthraquinone from suspensions which contain liquid nitrobenzene whereby in a first stage solid 1,5- and/or 1,8-dinitroanthraquinone with a content of less than 30% by weight of nitrobenzene is separated off mechanically from the suspension at elevated temperature and whereby in a second stage the residued nitrobenzene is removed from the separated 1,5- and/or 1,8-dinitroanthraquinone by lowering the pressure during which the temperature falls.
