    Abstract: The invention relates to a method for providing a purified crude gaseous C
    4 fraction (2) as an input stream for an extractive distillation using a selective solvent in order to obtain crude 1,3-butadiene on the basis of a liquid crude C
    4 -fraction (1) as a feed stream, containing C
    3 hydrocarbons, C
    4 oligomers, C
    4 polymers, and C
    5+ hydrocarbons together with butanes, butenes, and 1,3-butadiene. The method has the steps of 1) separating the C
    4 oligomers, C
    4 polymers, and C
    5+ hydrocarbons up to the respective residual content previously specified for the purified crude gaseous C
    4 fraction and 2) evaporating the liquid crude C
    4 fraction in an evaporator tank (VK). The invention is characterized in that the evaporator tank (VK) is associated with a stripping column (K) with one or more separating stages, the liquid C
    4 fraction (1) being fed to the stripping column in the upper region of the stripping column. The stripping column directly exchanges gas and liquid with the evaporator tank (VK) in the lower region of the stripping column, and the purified crude gaseous C
    4 fraction (2) is drawn off from the stripping column in the upper region. The stripping column (K) is operated without a condenser at the column head.

    Abstract: The invention relates to a method for extracting pure 1,3-butadiene by extractive distillation using a selective solvent from a C4 mixture (1) comprising, in addition to 1,3-butadiene, butanes, butenes and 0.5 to 3 wt % acetylene, relative to the total weight of the C4 mixture, characterized in that in a first process step a proportion of 90 to 99 wt %, relative to the total weight of the acetylene present in the C4 mixture, is selectively hydrogenated, resulting in a partially hydrogenated C4 mixture, that is subsequently processed into pure 1,3-butadiene in further process steps by extractive distillation and using the selective solvent, wherein the acetylene remaining in the partially hydrogenated C4 mixture is discharged in the process steps following the partial hydrogenation.

    Abstract: The invention relates to a method for producing an ethyleneamine mixture, wherein an aminonitrile mixture containing at least 30 wt. % aminoacetonitrile (AAN) and at least 5 wt. % iminodiacetonitrile (IDAN) is hydrogenated in the presence of a catalyst. Ethylenediamine (EDA) and/or diethylenetriamine (DETA) and optionally further ethyleneamines can be isolated from the resulting ethyleneamine mixtures.
