The invention relates to a process for preparing aminoalkanamides by reacting cyanoalkanoic esters with a) ammonia or an amine and b) hydrogen in the presence of a catalyst, the reaction with component b) being started simultaneously or not later than a maximum of 100 minutes after commencement of the reaction of the cyanoalkanoic ester with component a).

Method for the production of aminoalkane acid amides

A process for preparing N,N-dimethylacetamide (DMAC) by continuously reacting methyl acetate (MeOAc) with dimethylamine (DMA) in the presence of a basic catalyst, wherein MeOAc is used in the form of a methanolic solution which is obtained as a by-product in the preparation of polyTHF by transesterifying polyTHF diacetate with methanol.

Method for the production of N,N-dimethylacetamide (DMAC)

A process for preparing N,N-dimethylacetamide (DMAC) by continuously reacting methyl acetate (MeOAc) with dimethylamine (DMA) in the presence of a basic catalyst, wherein MeOAc is used in the form of a methanolic solution and the continuous distillative workup is effected in such a way that methanol and any other low boilers are initially removed overhead in a column A and the bottom effluent of column A is fed to a column B in which DMAC is removed via a side draw a purity of &#x2267;99.7% by weight.
