Abstract: In a continuous process for environment-friendly drying and purification of benzanthrone, the following process steps are applied: - charging a pumpable paste containing benzanthrone to a melt present in a stirred kettle, - dehydrating and melting the paste by means of steam, - condensing the water vapours emanating from the stirred kettle, - flaking off the melt present in the stirred kettle by means of a roll and - filling the flakes produced during flaking-off into a container.

Abstract: A process for the continuous preparation of ethylene- alpha -olefin copolymers by catalytic dry-phase copolymerisation of the monomers in a stirred or fluidised polymerisation zone, transfer of the resultant mixture of solid copolymer and unreacted gaseous monomers into a decompression zone, reduction of the pressure of the mixture, separation of the mixture into a gaseous phase and a solid phase, the solid phase being preflushed continuously with gaseous ethylene and subsequently being flushed with a mixture of nitrogen and steam, gives ethylene copolymers which have been very substantially freed from residual monomers, fragrances and flavours.
