    Abstract: The invention relates to a method for reprocessing a mixture, containing at least one alcohol of general formula (I) R
    1 -CH
    2 -CH
    2 -OH (I) or at least one branched alcohol of general formula (II) R
    1 -CH
    2 -CHR
    1 -CH
    2 -OH (II), at least one oil-soluble complex compound of at least one metal of the 8th, 9th, or 10th group of the periodic table of the elements, which is selected from complex compounds that have at least one ligand L
    1 that is at least bidentate, at least one coordination site of L
    1 being a nitrogen atom, and at least one acid of general formula (III) R
    1 -CH
    2 -COOH (III) in the form of a salt of said acid, the groups R
    1 being selected from C
    2 -C
    10 alkyl, linear or branched, characterized in that (a) the mixture is treated with water, which can contain an alkali metal hydroxide, (b) which extract/s salts of acid of general formula (III).

    Abstract: A process is proposed for preparing formic acid by reaction of carbon dioxide (1) with hydrogen (2) in a hydrogenation reactor (I) in the presence of a catalyst containing an element from group 8, 9 or 10 of the Periodic Table, of a tertiary amine containing at least 12 carbon atoms per molecule, and of a polar solvent comprising one or more monoalcohols selected from methanol, ethanol, propanols and butanols, and water, to form formic acid/amine adducts as intermediates, which are subsequently cleaved thermally, with workup of the outputs (3) from the hydrogenation reactor (I) in several process steps, a stream (13) comprising tertiary amine from the workup being used as a selective solvent for the catalyst.

    Abstract translation: 提出了一种通过在含有元素周期表第8,9或10族元素的催化剂存在下在氢化反应器(I)中使二氧化碳(1)与氢气(2)反应来制备甲酸的方法, 每分子包含至少12个碳原子的叔胺和包含一种或多种选自甲醇,乙醇,丙醇和丁醇的一元醇和水的极性溶剂以形成甲酸/胺加合物作为中间体,其随后被热裂解 在几个工艺步骤中处理来自氢化反应器(I)的输出物(3),包含来自处理的叔胺的物流(13)用作催化剂的选择性溶剂。
