    Abstract: The invention relates to a continuous method for separating out a solid, saline phase containing alkaline and/or alkaline earth acetates from the product mixture of the production of N,N-dimethylacetamide (DMAc) by reacting methyl acetate (MeOAc) with dimethylamine (DMA) in the presence of a catalyst containing N,N-dimethylacetamide (DMAc), methyl acetate (MeOAc), dimethylamine (DMA) and a catalyst, with the following method steps: level-regulated feeding of the product mix as a feed flow into an evaporation container of a forced circulation reboiler; flash evaporation of volatile components of the product mix in the forced circulation reboiler with the formation of a vapour phase containing N,N-dimethylacetamide (DMAc) and precipitation of a solid, saline phase containing alkaline or alkaline earth acetates; feed back of the volatile components of the product mixture obtained after flash evaporation; discharging an N,N-dimethylacetamide (DMAC) containing a vapour phase from the evaporator container as a discharge flow; concentration of the solid, saline phase containing alkaline or alkaline earth acetates in the forced circulation reboiling circuit of the forced circulation reboiler; separation of a partial flow comprising the solid, saline phase containing alkaline and/or alkaline earth acetates from the forced circulation reboiling circuit of the forced circulation reboiler; solid/liquid separation of the separated partial flow in at least one separator into a solid, saline phase containing alkaline and/or alkaline earth acetates and a liquid phase; and feeding of the liquid phase obtained after the solid/liquid separation back into the forced circulation reboiling circuit as a feedback flow. The method is characterized in that the volatile components of the product mix obtained after flash evaporation and the solid, saline phase containing alkaline and/or alkaline earth acetates are fed back into the evaporation container through an infeed which ends in a range from 30 cm above the level surface to 20 cm below the level surface of the fill level of the evaporation container.

    Abstract: The invention relates to a method for producing an amine by reacting a primary or secondary alcohol, aldehyde and/or ketone with hydrogen and a nitrogen compound, selected from the group containing ammonia and primary and secondary amines, in the presence of a supported catalyst that contains copper, nickel and cobalt. According to the invention, the catalytically active mass of the catalyst, prior to the reduction of the same using hydrogen, contains oxygen-containing compounds of aluminium, copper, nickel and cobalt and an amount ranging between 0.2 and 5.0 wt. % of oxygen-containing compounds of tin, calculated as SnO. The invention also relates to catalysts defined as above.
