    Abstract: The invention relates to a process for continuously preparing di-C1-3-alkyl succinates by reacting succinic acid with an C1-3-alkanol in the presence of a fixed-bed heterogeneous acidic esterification catalyst in a tubular reactor at a temperature in the range of from 60 to 100° C., wherein a mixture, comprising succinic acid, C1-3-alkanol, mono-C1-3-alkyl succinate, di-C1-3-alkyl succinate and water, is formed in a mixing stage and fed to the entrance of the tubular reactor, and wherein 5 to 75% of the outlet flow rate of the tubular reactor are recycled directly to the mixing stage as a recycle stream, and the molar ratio of C1-3-alkanol to succinic acid added to the mixing zone, and not including the C1-3-alkanol and succinic acid at the recycle stream, being in the range of from 2.0 to 9.5. The invention furthermore relates to a process for separating the reactor effluent of an esterification of succinic acid with an C1-3-alkanol to give di-C1-3-alkyl succinates by distillation, wherein the separation is performed in a divided wall column in which C1-3-alkanol and water are removed in a top draw of the column, di-C1-3-alkyl succinate is removed in a side draw of the column, and wherein mono-C1-3-alkyl succinate and succinic acid are removed in a bottom draw of the column.

    Abstract: The invention relates to a method for extracting aromatic compounds from aqueous, alkaline compositions containing lignin, which have a pH value of at least pH 10, in particular of at least pH 11, especially of at least pH 12, characterized in that the aqueous, alkaline composition containing lignin is treated with active carbon, the active carbon separates from the aqueous, alkaline composition containing lignin and the active carbon then undergoes a desorption step in order to extract the aromatic compounds, wherein the desorption step comprises the treatment of the active carbon (i) by means of an organic solvent, which essentially consists of one or more aromatic hydrocarbons or a mixture of at least one aromatic hydrocarbon together with at least one C
    1 -C
    4 alkanol, or (ii) by means of water vapor, wherein an eluate is obtained which contains the aromatic compounds.
