    摘要： The invention relates to a method for producing formic acid formates, whereby (a) formic acid methyl ester is partially hydrolysed with water; (b) formic acid methyl ester and methanol are separated by distillation from the reaction mixture obtained in step (a), forming a current containing formic acid and water; (c) the current obtained in step (b), containing the formic acid methyl ester and optionally methanol, is converted into a current containing formate and water, by (i) reaction with a basic compound having a pKa value of the corresponding acid of the corresponding dissociation step of =3, measured at 25° C. in an aqueous solution, in presence of water, and (ii) separation by distillation of the methanol; and (d) the current obtained in step (b), containing formic acid and water, and the current obtained in step (c), containing formate and water, are combined to form a mixture containing the formic acid formate and water. The invention also relates to a device for producing said formic acid formates and to the use of the same.

    摘要： A process for the preparation of a metal-doped support material. The metal-doped support material comprises at least one metal in elemental form on at least one support material which is based on carbon by gas-phase deposition of at least one compound comprising the at least one metal in the oxidation state 0 in combination with carbon monoxide on the at least one support material and thermal decomposition of the at least one compound comprising the at least one metal in the oxidation state 0 in order to obtain the at least one metal in elemental form. During and after the deposition and the decomposition, the support material is not brought into contact with reducing compounds during the preparation.
